基于FLAC3D的调压井开挖三维应力应变分析
Three-dimensional Stress-strain Analysis of Surge Chamber Structure by FLAC3D
摘要
Abstract
In this study, FLAC3D software was employed to proceed 3-D nonlinearly simulating analysis on surge chamber structure for a hydropower station.The elastic-plasticity constitutive equations were used to establish numerical model of surge chamber structure, and geometrical boundary condition, initial ground stress and excavation works were simulated.In the model, the anchor arms elements were located in the surround rock of surge chamber structure on the excavating process.Stress-strain of structure had been analyzed, The stability of surround rock was evaluated.关键词
