摘要: 通过非线性二维有限元计算,对水布垭地下电站洞室开挖围岩的应力与变形进行了分析,探讨了主厂房洞室局部软岩置换、喷锚支护等措施对围岩开挖位移与应力的影响。在此基础上,对设计采用的各种支护处理措施的加固效果以及地下厂房洞室围岩的整体稳定性作出评价。

Abstract: The stress distribution and deformation of the surrounding rock mass in the underground powerhouse of the Shuibuya Project are analyzed by using nonlinear 2D FEM. Furthermore, the influences of support measures including the replacement of soft rock mass and shotcrete-bolt support on the stress and deformation of the surrounding rock mass are studied. Finally, the integrate stability of the underground powerhouse is evaluated.
