基于有限差分法的水库透水性能研究

Research on Permeability Performance of Reservoir based on Finite Difference Method

水库大坝是利国利民的重要基础设施。在水库建设中,渗流问题与透水问题是影响水库安全稳定的重要因素。以山东省某土石坝为例,采用基于有限差分法的FLAC软件,并结合强度折减法对大坝进行渗流和稳定性分析,探讨了不同修建阶段建模方法下大坝的位移、孔隙水压力和渗流等特征。研究结果可为相关工程提供参考。

Reservoir dam is an important infrastructure that benefits the country and the people.In reservoir construction,seepage and permeability issues are important factors affecting the safety and stability of the reservoir.Taking an earth-rock dam in Shandong Province as an example,this paper uses FLAC software based on finite difference method and strength reduction method to analyze the seepage and stability of the dam,and discusses the characteristics of displacement,pore water pressure and seepage of the dam under different modeling methods in different construction stages.The research results can provide reference for relevant projects.
