摘要
本文以拟建水库大坝为例计算了位于断层附近的坝址区在发生6~7级地震时的位移、应变和应力。结果表明这种位移、应变和应力都达到很大的值,对于近断层的重大工程设施必须考虑断层发震产生的震后变形引起的“抗断问题”。
Taking a planed reservoir dam as the example, the displacement, strain and stress in the dam area which is located near active fault in M 6 - 7 earthquake are calculated in this paper. The results show that the deformation can reach a higher values and cause serious damage to structure. So the ' antirupture problem' must be considered for the important and great engineering near active fault.
