【摘要】 采用二维弹塑性有限元方法,对水布垭地下厂房引尾水洞软岩段洞室围岩开挖、喷砼支护进行模拟,研究洞室开挖和喷砼后围岩的变形与应力。针对尾水洞洞群,研究不同施工开挖方式对洞室围岩应力应变的影响。更多还原

【Abstract】 In this paper,the 2D finite element method is aplied to simulate excavation and shotcrete at weak rockmass of tailwater caves inunderground houses of Shuibuya hydraulic power station and to calculate the displacement and stress of the rockmass after excavation andshatcrete.For the tailwater caves,the deformation and stress of rockmass in a different construction ways is discussed.更多还原
