摘要
水力劈裂是影响坝体安全运行的重要问题之一。为了检验观音岩水电站坝体的安全性,根据现场坝料干密度试验得到的坝料力学参数重新进行三维有限元静力计算分析,并用总应力法对坝体进行大坝水力劈裂的复核,计算结果表明,接头部位发生水力劈裂的可能性极小。
Hydraulic fracturing is one of most important issues that affect the safe operation of dams. In order to check the safety of the dam in Guanyinyan Hydropower Station, the three-dimensional finite element static analysis of Guanyinyan Dam is conducted again according to dam material mechanical parameters which obtained by site dam material dry density tests, and the hydraulic fracturing of dam is reviewed by using total stress method. The results show that the possibility of hydraulic fracturing in junction position of Guanyinyan composite dam is very low.
