摘要

针对黄河公伯峡水电站工程进水口5#坝段坝基稳定问题，根据断层切割情况，建立了三维极限平衡计算模型，推导了楔形体三维抗滑稳定计算公式，计算了不同工况条件下的抗滑稳定安全系数，计算结果表明其抗滑稳定满足规范要求。

Abstract

The stability of the 5th dam block of the intake of the Gongboxia hydroelectric power station is analyzed. Firstly

according to geological conditions

three-dimensional models are established. Then

the three- dimensional limit equilibrium calculation formula is deduced. Finally

the safety factors of sliding stability for different working conditions are calculated. The results show that the dam block is safe.
