摘要
指出可能影响混凝土拱坝安全的关键点为拱坝坝肩的稳定。阐述坝肩稳定评价中主要包括的4个方面内容:坝肩岩体的模拟方式,坝体和坝肩的联合作用,失稳机理和失稳判据。从这4个方面详细阐述了岩体的模拟方法、坝肩安全稳定分析方法和判断准则,以及失稳机理,并对各个方面加以简要评价,指出了目前较为适用的方法和准则,给出了一些建议。
It is pointed out that the stability of the dam abutment is a key factor affecting the safety of concrete arch dams. Its stability evaluation should be performed from the following aspects, i.e. the method of rock simulation, the co-action of the darn and abutment, the mechanism of abutment instability, and the criterion of instability. Based on a detailed analysis and brief evaluation, some effective methods and eritera are given, and some suggestions are made.
