摘要
选取清江水布垭水利枢纽工程地下厂房区,采用三维快速拉格朗日法(FLAC-3D),模拟施工开挖过程,研究了复杂地质条件下洞室群围岩的开挖变形形态与应力状态,分析了围岩塑性区分布及地下厂房洞室群围岩的稳定性,并对尾水洞顶拱进行了加固处理。
The construction and excavation process of underground plant of the Shuibuya Project are simulated by three-dimensional fast Lagrangian method(FLAC-3D). The pattern of deformation caused by excavation and stress state in surrounding rocks of the chamber group under complex geological conditions are researched. The distribution of plastic areas and the stability of surrounding rocks are analyzed. And the bolting is performed to support the vault of tail-race tubes.
