为了对林溪水库挡水坝进行稳定性监测,利用有限元方法,对坝体的力学性能进行计算模拟.同时,采用强度折减法,对该坝坝坡稳定性进行计算.结果表明,上游水位高程71.29m时的渗流量有限元结果为69.1m3/d;当水库处于死水位时,黏土心墙逸出点渗透坡降为0.896,不会出现渗透破坏;3 种工况下,坝坡抗滑稳定安全系数分别为1.43、1.29 和 1.21,均未超过限定值.研究结果可为大坝的除险加固和管理提供参考.
Research on Stability Monitoring of Dam Body of Hydraulic Engineering Based on Finite Element Method
To monitor the stability of the retaining dam of Linxi reservoir,the finite element method is used to calculate and simulate the mechanical properties of the dam.At the same time,the stability of the dam slope was calculated using the strength reduction method.The results show that the finite element analysis of seepage flow at the upper water level of 72.19m is 69.1m3/d.When the reservoir is at the dead water level,the dam body is reduced to 0.896,and there is basically no seepage damage.The safety factors of anti-sliding stability of dam slope under the three working conditions are 1.43,1.29 and 1.21 respectively,which do not exceed the limit value.The research provides a very important reference value for dam reinforcement and management.
