高拱坝整体稳定地质力学模型综合法试验与数值分析
Experiment and numerical analysis on global stability of high arch dam geomechanical model
摘要
Abstract
The site of Dagangshan arch dam are featured with complicated geologic structures of various types of dikes,faults,joints and fissures,and its global stability is greatly influenced by these structures.In this work,methods of geomechanical model test and 3D nonlinear FEM calculation were used to study the global stability,including an analysis on geological defects,dam deformation,abutment displacements,failure process and failure mechanism.This analysis shows global safety factors of 5.0 ～5.6 by model test and 5.6 ～ 6.0 by FEM computation.On the basis of these factors,dam safety is evaluated and reinforcement measures are suggested.关键词
