Anti-Seismic Monument
The Anti-Seismic Monument or Tangshan Earthquake Monument is located in the eastern part of the center square in Tangshan City, and the Tangshan Earthquake Memorial Hall museum is on the western part of the square. The Monument Square measures 320 m long from east to west and 170 m wide from south to north, covering an area of 5.4 hectares. It is a monument to the city's dauntless spirit. Description The Anti-Seismic Monument is composed of main monument and a secondary monument. The main monument tells the heroic stories of earthquake relief. The secondary monument describes the history of the Tangshan earthquake in the form of ruins. The monument's pedestal is 3 m high and the body is 30 m high. The body is composed by four trapezoidal pillars. The pillars symbolize the buildings which collapsed during the earthquake and the new architecture which soars above the horizon. The top of the pillars resembles four huge hands reaching the sky and symbolizing that "Mankind Can Conqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tangshan
Tangshan () is a coastal, industrial prefecture-level city in the northeast of Hebei province. It is located in the eastern part of Hebei Province and the northeastern part of the North China Plain. It is located in the central area of the Bohai Rim and serves as the main traffic corridor to the Northeast. The city faces the Bohai Sea in the south, the Yan Mountains in the north, Qinhuangdao across the Luan River to the east, and Tianjin to the west. Much of the city's development is thanks to the industrialization, beginning in 1870, when Kailuan Group established coal mines in the region. It's the birthplace of China's first standard-gauge railway, the first railway plant, the first steam locomotive, and the first cement factory. It was hailed as China's "cradle of industrialization". Even today, Tangshan is a hub of steel, energy, chemical, and ceramics production. Ping opera, which originated from the city's Luanzhou county, is one of the five most popular Chinese operas. T ...

Disaster Relief
Emergency management or disaster management is the managerial function charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies, which can be understood as minor events with limited impacts and are managed through the day to day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also common.

1976 Tangshan Earthquake
The 1976 Tangshan earthquake () was a 7.6 earthquake that hit the region around Tangshan, Hebei, China, at 3:42 a.m. on 28 July 1976. The maximum intensity of the earthquake was XI (''Extreme'') on the Mercalli scale. In minutes, 85 percent of the buildings in Tangshan collapsed or were rendered unusable, all services failed, and most of the highway and railway bridges collapsed or were seriously damaged. The official report claimed 242,769 deaths and 164,851 serious injuries in Tangshan, but when taken into account the missing, the injured who later died and the deaths in nearby Beijing and Tianjin, scholars accepted at least 300,000 died, making it the deadliest earthquake in China and among the top disasters in China by death toll. The earthquakes The Tangshan earthquake was composed of two main shocks. The first struck at 3:42:56 in the morning (local time), approximately 12 km under the southern part of Tangshan.. The was initially estimated at 8.1, subsequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trapezoid
A quadrilateral with at least one pair of parallel sides is called a trapezoid () in American and Canadian English. In British and other forms of English, it is called a trapezium (). A trapezoid is necessarily a Convex polygon, convex quadrilateral in Euclidean geometry. The parallel sides are called the ''bases'' of the trapezoid. The other two sides are called the ''legs'' (or the ''lateral sides'') if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases). A ''scalene trapezoid'' is a trapezoid with no sides of equal measure, in contrast with the #Special cases, special cases below. Etymology and ''trapezium'' versus ''trapezoid'' Ancient Greek mathematician Euclid defined five types of quadrilateral, of which four had two sets of parallel sides (known in English as square, rectangle, rhombus and rhomboid) and the last did not have two sets of parallel sides – a τραπέζια (''trapezia'' literally "a table", itself fr ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars ( rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Hu Yaobang
Hu Yaobang (; 20 November 1915 – 15 April 1989) was a high-ranking official of the People's Republic of China. He held the top office of the Chinese Communist Party (CCP) from 1981 to 1987, first as Chairman from 1981 to 1982, then as General Secretary from 1982 to 1987. Hu joined the CCP in the 1930s, and rose to prominence as a comrade of Deng Xiaoping. During the Cultural Revolution (1966–1976), Hu was purged, recalled, and purged again by Mao Zedong. After Deng rose to power, following the death of Mao Zedong, Hu played a role in the "Boluan Fanzheng" program. Throughout the 1980s, Hu pursued a series of economic and political reforms under the direction of Deng. Hu's political and economic reforms made him the enemy of several powerful Party elders, who opposed free market reforms and Hu's reforms of China's government. When widespread student protests occurred across China in 1987, Hu's political opponents blamed Hu for the disruptions, claiming that Hu's "laxness" ...

Monuments And Memorials In China
A monument is a type of structure that was explicitly created to commemorate a person or event, or which has become relevant to a social group as a part of their remembrance of historic times or cultural heritage, due to its artistic, historical, political, technical or architectural importance. Some of the first monuments were dolmens or menhirs, megalithic constructions built for religious or funerary purposes. Examples of monuments include statues, (war) memorials, historical buildings, archaeological sites, and cultural assets. If there is a public interest in its preservation, a monument can for example be listed as a UNESCO World Heritage Site. Etymology It is believed that the origin of the word "monument" comes from the Greek ''mnemosynon'' and the Latin ''moneo'', ''monere'', which means 'to remind', 'to advise' or 'to warn', however, it is also believed that the word monument originates from an Albanian word 'mani men' which in Albanian language means 'remember ...
