摘　　要：黄土沟壑地区水库库区存在不良物理地质现象,水库蓄水后高陡黄土岸坡将会产生不同程度的塌滑,对大坝的安全构成威胁,且侵占部分库容。以山西省保德县李家湾水库工程为例,在地质勘探、土工试验基础上,对高陡黄土岸坡进行库岸坍塌带宽度预测;运用高边坡稳定分析数学模型进行计算论证,得出稳定开挖边坡坡率,并提出一系列工程治理措施,为典型黄土地貌山区的同类型工程设计提供参考。After reservoir impoundment, high-steep slope collapse and sliding of different de-gree occurrs, which can be a severe threat to dam security by encroaching part of reservoir capaci-ty and influencing storage capacity of the reservoir. In this paper, we predicted the width of res-ervoir banks collapse on the basis of geological exploration and soil test for high-steep soil slope;obtained stable excavated slope ratio through calculation evaluation of the mathematical model forthe stability analysis of high slope; and put forward some engineering control measures to providereference for the similar project design for mountain area of typical loess geomorphology.
