North Breakwater Dome
The is a long arched " semi-domical" structure in the port area of Wakkanai, Hokkaidō, Japan. Rising to a height of above the sea and extending some , with seventy columns, an intercolumniation of , and a width from column to wall of , the form, inspired by a Roman arcade, is said to be without parallel. History In accordance with the 1905 Treaty of Portsmouth, South Sakhalin was incorporated into the Empire of Japan and governed as Karafuto Prefecture. To improve maritime connections between Wakkanai and Sakhalin, between 1910 and 1919 plans were laid for the redevelopment of the old fishing port of Wakkanai, with civil engineer in charge. Measures included a north breakwater to protect the port from windstorms and high waves, paired with a sand groin to the south to enclose the port, together with land reclamation and the construction of moorings. Initial plans for the north breakwater were for its parapet to rise to a height of , but this was considered insufficient to wi ...

Breakwaters
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Cape Sōya
is the northernmost point of the island of Hokkaidō, Japan. It is situated in Wakkanai, Sōya Subprefecture. The is at the cape, although the true northernmost point under Japanese control is a small deserted island called Bentenjima, northwest. Since the cape is just away across La Perouse Strait from Cape Crillon, Sakhalin Island, Russia, it is possible to catch a glimpse of the island of Sakhalin on a clear day. There are more than ten monuments at Cape Sōya, including the Monument of the northernmost Point of Japan, the Tower of Prayer (a memorial to Korean Air Lines Flight 007, shot down in 1983), a statue of Mamiya Rinzō, the Monument of Peace (a memorial to the sunken submarine , and others). Sōya Misaki settlement, east of the cape, has many facilities known to be "the northernmost in Japan", such as the northernmost lighthouse ( Cape Sōya Lighthouse), the northernmost filling station (Idemitsu Cape Sōya SS), the northernmost elementary school (Ōmisaki Element ...

Frost Weathering
Frost weathering is a collective term for several mechanical weathering processes induced by stresses created by the freezing of water into ice. The term serves as an umbrella term for a variety of processes such as frost shattering, frost wedging and cryofracturing. The process may act on a wide range of spatial and temporal scales, from minutes to years and from dislodging mineral grains to fracturing boulders. It is most pronounced in high-altitude and high-latitude areas and is especially associated with alpine, periglacial, subpolar maritime and polar climates, but may occur anywhere at sub-freezing temperatures (between -3 and -8 °C) if water is present. Ice segregation Certain frost-susceptible soils expand or heave upon freezing as a result of water migrating via capillary action to grow ice lenses near the freezing front. This same phenomenon occurs within pore spaces of rocks. The ice accumulations grow larger as they attract liquid water from the surrounding ...

Nevelsk
Nevelsk (russian: Не́вельск; ja, 本斗, ''Honto'') is a port town and the administrative center of Nevelsky District of Sakhalin Oblast, Russia, located on the southwest coast of the Sakhalin Island, from Yuzhno-Sakhalinsk, the administrative center of the oblast. Population: History The first Russian settlers founded a village on the present site of Nevelsk in 1789. The region was the site of a struggle for control between the Russians and Japanese. After the Treaty of Shimoda officially transferred the southern Kuril Islands to Japan in 1855, the settlement was placed under joint Russian-Japanese administration under the name Honto it comes from the Ainu language. Honto reverted to complete Russian administration in 1875, as the Treaty of Saint Petersburg gave control of all the Kuril Islands to Japan, in exchange for complete Russian sovereignty over the island of Sakhalin. It then returned to Japanese rule in 1905, after the Treaty of Portsmouth ceded south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korsakov (town)
Korsakov is a town and the administrative center of Korsakovsky District of Sakhalin Oblast, Russia. It is located south from Yuzhno-Sakhalinsk, at the southern end of Sakhalin Island, on the coast of the Salmon Cove in the Aniva Bay. The town has a population of 33,526 as of the 2010 census. History Little is known of the early history of Korsakov. The site was once home to an Ainu fishing village called Kushunkotan (in Russian sources, Tamari-Aniva), which was frequented by traders of the Matsumae clan from as early as 1790. On September 22, 1853, a Russian expedition, commanded by Gennady Nevelskoy, raised the Russian flag at the settlement and renamed it "Fort Muravyovsky", after Governor-General of Eastern Siberia Nikolay Muravyov.The Occupation of Southern Saghalin by the Russians in 1853–54', Akizuki Toshiyuki, Hokkaidō University.

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] |
Deep Foundation
A deep foundation is a type of foundation that transfers building loads to the earth farther down from the surface than a shallow foundation does to a subsurface layer or a range of depths. A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper. Some of the common reasons are very large design loads, a poor soil at shallow depth, or site constraints like property lines. There are different terms used to describe different types of deep foundations including the pile (which is analogous to a pole), the pier (which is analogous to a column), drilled shafts, and caissons. Piles are generally driven into the ground in situ; other deep foundations are typically put in place using excavation and drilling. The naming conventions may vary between engineering discip ...
