摘要
基于云南某水电站地下洞室的地质勘察及设计资料,通过ANSYS建立其三维地质模型,经FLAC3D数值模拟计算,系统研究了该水电站地下洞室开挖及支护后围岩的应力场、应变场和塑性破坏区的变化特征,对其围岩稳定性做出评价,为洞室设计提供了科学依据与技术指导。
Based on data of geological investigation and design of the underground cavern of one hydropower project in Yunnan province, its 3D geological model is built with ANSYS. By the value simulation calculation of FLAC3D, the change characteristics of stress field, strain field and plastic failure zone of the surrounding rock of the underground cavem during excavation and after support are studied systematically. Meanwhile, the stability of the surrounding rock is assessed. This study provides the cavern design with scientific basis and technical guid- ance.
