本文对岩基上混凝土重力坝抗滑稳定性问题,就我国和美、苏等国家目前对坝基接触面和基岩内部不连续面上的稳定安全性指标的计算方法,进行了简要的介绍。对美、苏等国的规范作了简单描述,对各种计算方法的适用范围,理论依据和选用这些计算或实验来进行坝基稳定设计时,应注意的条件,作了较充分的阐述,并对不同方法,提出了作者的一些看法,可供设计和科技工作者参考。
In this paper, the stability of concrete gravity dams on rock foundations is discussed briefly. The calculation methods for stable safety indicators on the interface between dam foundations and the internal discontinuous planes of bedrocks in China, the United States, and the Soviet Union are briefly introduced. The specifications of the United States, the Soviet Union and other countries are briefly described. The scope of application of various calculation methods, the theoretical basis, and the selection of these calculations or experiments for the stable design of dam foundations have been fully explained. For the different methods, some author’s views were put forward, which could be used for design and scientific and technological workers’ reference.
