摘要
对惠州抽水蓄能电站地下厂房洞室围岩的稳定性进行了二维弹塑性有限元计算.对地下电站洞室开挖围岩的应力与变形进行了分析,探讨了施加系统锚杆和喷混凝土等支护措施对围岩的加固作用,研究了开挖顺序调整、间距改变以及扩挖对围岩稳定性的影响。
The distribution of stress and deformation of the surrounding rock masses in underground powerhouse of Huizhou pump-storage plant is analyzed using nonlinear 2D FEM.Furthermore,the influences of support measures with shotcrete-bolt on the stress and deformation of surrounding rock masses are studied.The effects of excavation sequence,interval and expanding excavation are studied on the stability of surrounding rock masses.
