本文通过对铜街子大坝深层抗滑稳定的大量计算,分析了抗力体对大坝安全度的影响;用点的强度破坏理论分析了岩体的破裂面;并对如何正确地使用纯摩与剪摩指标提出了新的见解。
In this paper, a large number of calculations of the deep anti-sliding stability of the Tongjiezi Dam are carried out. The influence of the anti-body on the safety of the dam is analyzed. The rupture plane of the rock mass is analyzed by the strength failure theory of the point. And shear friction indicators put forward new ideas.
