摘　　要：重力坝抗滑稳定分析中,如果滑裂面强度参数较低,抗滑稳定计算难以达到规范要求的3.0的允许安全系数。收集国内一些典型水利工程的设计实例,经过实例验算和对比分析,提出抗剪公式的适用性及其安全系数的推荐值。结论指出,对于凝聚力很低的软弱结构面,可用抗剪公式进行计算,并采用与之配套的安全系数。In the stability analysis of gravity dam foundation,the safety factor is hard to achieve the permissible value when the intensity parameter of the structural plane is low.Here,based on several engineering design examples in China and by checking computations and comparisons,the applicability and recommended safety factors of the shear resistant formula are put forward.The result shows that the shear resistant formula could be applicable for flabbily structural planes,and the safety factors suitable for the formula are also adopted.
