地震是具有巨大破坏力的自然现象,它往往给人类带来重大灾害;特别是混凝土高坝受地震影响万一失事,大量库水一泻千里,更将造成不可估量的损失。我国兴建的混凝土高坝较多,这些地区绝大部分都有频繁的地震活动,因此研究混凝土坝的抗震问题具有 Earthquake is a natural phenomenon with great destructive power. It often brings great disasters to human beings. In particular, if concrete high dam is affected by earthquake, large amount of reservoir water will flow in a big way and will inevitably cause immeasurable loss. In our country, there are many concrete high dams, and most of these areas have frequent seismic activities. Therefore, it is necessary to study the seismic resistance of concrete dams with
