日前,苏联正在设计和修建萨扬舒申斯克、努列克、罗贡等一系列举世无双的水利水电工程。通常这类建筑物都位于高地震活动性的山区。因此,设计中坝体的抗震计算能否相当精确地反应出它的工作特性具有重要的意义。尤其坝体本身是几何形状非常复杂的巨大块件,因而在计算它的抗震性时必 A few days ago, the Soviet Union was designing and constructing a series of unparalleled water conservancy and hydropower projects such as Sayan Shusinsk, Nurek, and Luogong. Often such buildings are located in high seismically active mountains. Therefore, it is of great significance that the seismic calculation of the dam can accurately reflect its working characteristics. In particular, the dam body itself is a massive piece with a very complex geometric shape and must be calculated when calculating its seismic resistance.
