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。
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.
