| 摘 要： | 在阐述层状岩质边坡岩性组合分类和地下水分布特征的基础上，介绍了考虑残坡积层孔隙水和裂隙潜水控稳作用的边坡稳定性计算方法，根据小浪底水利枢纽工程若干边坡有的有限元计算，结果表明：考虑包气带裂隙水作用时，边坡安全系数可降低5％－15％；当库水位聚降时，裂隙潜水对边坡稳定性也有重要影响。

| Abstract: | On the basis of the combination and classification of the lithological character and the feature of underground water distribution, a slope stability calculation method is introduced, which includes the effect of pore water in the eluvial slope, fissure water in the aerated zone and fissure phreatic water. The finite element calculation for many slopes of Xiaolangdi Multipurpose Dam Project proves that the safety factor will reduce by 5%～15% when fissure water in the aerated zone is considered and that fissure phreatic water has a large effect on the slope stability when the reservoir water level falls suddenly. |
