Guangzhao Dam
The Guangzhao Dam is a concrete gravity dam on the Beipan River near Guangzhao in Guanling County, Guizhou Province, China. The main purpose of the project is hydroelectric power generation with additional purposes of water regulation and irrigation. It creates the uppermost or head reservoir on the Beipan and was constructed between 2003 and 2008. Construction Construction on the dam began in May 2003 and the river was diverted in October 2004. Reservoir filling began in 2007 and by 2008, the dam and power plant were complete. On June 28, 2010, a landslide in the area of the dam that killed 99 locals was believed to be caused by seismic effects from the reservoir. Specifications The dam is tall and wide and composed of roller-compacted concrete Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Guizhou Province
Guizhou (; formerly Kweichow) is a landlocked province in the southwest region of the People's Republic of China. Its capital and largest city is Guiyang, in the center of the province. Guizhou borders the autonomous region of Guangxi to the south, Yunnan to the west, Sichuan to the northwest, the municipality of Chongqing to the north, and Hunan to the east. The population of Guizhou stands at 38.5 million, ranking 18th among the provinces in China. The Dian Kingdom, which inhabited the present-day area of Guizhou, was annexed by the Han dynasty in 106 BC. Guizhou was formally made a province in 1413 during the Ming dynasty. After the overthrow of the Qing in 1911 and following the Chinese Civil War, the Chinese Communist Party took refuge in Guizhou during the Long March between 1934 and 1935. After the establishment of the People's Republic of China, Mao Zedong promoted the relocation of heavy industry into inland provinces such as Guizhou, to better protect them from ...

Beipan River
Beipan River () is a river in Guizhou and Yunnan provinces, China, and part of the great Pearl River basin. Other names The upper reaches in Yunnan and Guizhou were once known as the Zangke River. Course The Beipan River passes through the modern Chinese provinces of Yunnan and Guizhou. When reaching the border of Guangxi, the Beipan River (literally, the Northern Pan River) merges with the Nanpan River (the Southern Pan River), forming the Hongshui River, which continues to the southeast. History The river was significant in history as a communications pathway between the Yelang and Nanyue kingdoms. Bridges The river is crossed by the Duge Bridge, the world's highest, the Qinglong Railway Bridge, the Guanxing Highway via the Beipan River Guanxing Highway Bridge, the Liupanshui-Baiguo Railway via the Beipan River Shuibai Railway Bridge, and the G60 Hukun Expressway via the Beipan River Hukun Expressway Bridge. All of these bridges are among the highest in the world. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Roller-compacted Concrete
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers. In dam construction, roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Outlet Works
A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very elaborate. Background A set of outlet works is a device used to release and regulate water flow from a dam. Such devices usually consist of one or more pipes or tunnels through the embankment of the dam, directing water usually under high pressure to the river downstream. These structures are usually used when river flow exceeds the capacity of the power plant or diversion capacity of the dam, but do not have flows high enough to warrant the use of the dam spillways. They may also be utilized when river flows must be bypassed due to maintenance work in the power station or diversion gates. Although similar in purpose to spillways, outlet works provide a more controlled release to meet downstream flow requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams In China
Dams and reservoirs in China are numerous and have had a profound effect on the country's development and people. According to the World Commission on Dams in 2000, there were 22,104 dams over the height of operating in China. Of the world's total large dams, China accounts for the most – of them; of which are used for irrigation. Accordingly, the oldest in China still in use belongs to the Dujiangyan Irrigation System which dates back to 256 BC. In 2005, there were over 80,000 reservoirs in the country and over 4,800 dams completed or under construction that stands at or exceed in height. As of 2007, China is also the world's leader in the construction of large dams; followed by Turkey, and Japan in third. The tallest dam in China is the Jinping-I Dam at , an arch dam, which is also the tallest dam in the world. The largest reservoir is created by the Three Gorges Dam, which stores 39.3 billion m3 (31,900,000 acre feet) of water and has a surface area of . Three Gorges is al ...

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...
