庞庄水库左坝肩岩体稳定性评价

山西省太谷县庞庄水库左坝肩岩石夹有稳定性较差的软弱岩组，在地质构造作用和长期受浸状态下易软化、泥化，抗剪强度降低，形成软弱结构面，易形成潜在滑移面，影响大坝稳定。针对此问题进行了定性、定量的分析和评价，并提出了处理建议。

Analysis on the Stability of the Rock Mass of Pangzhuang Reservoir's Left Dam Shoulder

There are some weak rock groups within the rock mass of Pangzhuang Reservoir's left dam shoulder, Taigu County, Shanxi Province, under the geological structural action and long-period soaking, these rock groups are easily softened and argillized, their shear strength will be decreased, forming the weak structural plane and the latent slip plane and influencing the stability of the dam. This paper makes qualitative and quantitative analysis and evaluation on this problem, and puts forward some treating suggestions.
