【摘要】 采用二维弹塑性有限元方法,对构皮滩导流洞软岩段围岩开挖、喷锚支护进行合理的模拟,研究洞室开挖过程及开挖完成后围岩的应力应变状态、变形大小及塑性区的分布,并对喷锚支护效果作出评价。
【Abstract】 In this papers, the elasto-plastic finite element method is applied to simulate the excavation and reinforcement of the diversion tunnelwith soft rock at the GouPiTan hydroelectirc station. It is analyzed the displacement and stress of surrounding rock mass after excavating.Based on the computing results, the stability of the diversion tunnel in the soft rock zone is evaluated.
