大坝技术及长效性能研究进展(英文版)(精)

目 录内容简介
The development of concrete gravity dams dated back from the end of the 19th century. After entering the 20m century. with the rapiddevelopment of concrete construction technology and construction machinery, the material for constructing gravity dams evolved from masonry to concrete. Due to its distinct advantages in simple structure, safety and reliabilfty, and construction convenience, etc, relevanttechnologies of concrete gravity dams have developed quickly and gradually formed a complete modern technology system. In 1962.the Grand Dixence Dam with a height of 285 m. the highest concrete gravity dam in the world, was constructed in Switzerland In 2010.China completed the construction of Three Gorges Proiect, the largest hydraulic project in the world. The Three Gorges Dam is a concretegravity dam with a height of 181m.The development of concrete arch dams also dated back from the end of the 19th century. The United States was the first country todevelop modern technologies for constructing gravity arch dams. At the beginning of 20th century, United States began to construct highconcrete arch dams. In 1936, Hoover Gravity Arch Dam with a height of 221.4 m was constructed in U.S. Due to its prominent advantagesin economy and safety, concrete arch dams are widely adopted around the world. In 1978, the Inguri Arch Dam with a height of 2715m.the highest concrete arch dam in the world at the time. was constructed in Georgia. In 2010, China built Xiaowan Arch Dam with a height of 292 m, which is the highest among those concrete arch dams constructed in the world up to now. Currently, China is building Jinping-IConcrete Arch Dam with a height of 305 m, which is the highest among those concrete arch dams under construction in the world.Based on the previous progress achieved and the successful practices of the international milestone projects, great achievements will bemade by further research works and engineering practices in the future.
