本文采用刚体─弹簧元法 ,对不同强度参数理论 (昆明院推荐参数、按断裂力学理论所推纯摩系数、Hoek剪摩修正参数 )下的小湾高拱坝坝肩 (基 )纯摩及剪摩静力安全系数进行了计算评价。对 5 8个不同高程滑出的坝肩抗力体滑块的搜索分析表明 ,控制滑块为低高程滑块 ,在增设坝后排水的条件下 ,小湾坝肩静力稳定性可以满足规范要求
In this paper, the rigid-body-spring element method is used to simulate the dam abutment (base) of the Xiaowan high arch dam under different strength parameters (Kunming recommended parameters, pure friction coefficient according to the theory of fracture mechanics and Hoek shear friction correction parameters) Shear friction safety factor was calculated and evaluated. The search analysis of 58 dam abutment body slides with different elevation slides out shows that the control slides are low elevation slides. The static stability of the dam abutment can meet the standard requirements
