宽缝重力坝深层抗滑稳定分析

Stability Analysis on the Deeper-layer Antiskiding of Wide-seam Gravity Dams

某宽缝重力坝右F15断层为顺河向、缓倾角大断层,空间结构非常复杂,施工时未充分认识和认真处理,是影响大坝安全运行的控制因素。文中利用刚体平衡法分析沿F15断层面的抗滑稳定,探讨各种影响因素,提出综合评价意见。

The right F15 fault of certain wide-seam gravity dam is a riveralong slow-inclination huge fault, its space structure is very complex. Insufficient recognition and unserious treatment in the construction are control factors influencing the safety operation of the dam. In this paper, the rigid-body balance method is used to analyse the stability of antiskiding along F15 fault face, and explore various influence factors, and the comprehensive evaluation opinions are put forward.
