| 摘 要： | 根据实际现场调查情况,论述了土质边坡冻融失稳的主要原因及影响边坡冻融失稳的主要因素.考虑了地下水的渗流作用,建立了冻土边坡冻融失稳稳定性分析几何模型.采用有效应力法,分别把土和水的混合体当作研究对象和把土骨架作为研究对象,得出二种方法在求季冻区土质边坡冻融失稳的稳定性系数时,会得到一致的结果.

| Abstract: | Based on the investigation on the spot,the main reasons for freeze and melt related loss of stability of earthen side slopes and major relevant affecting factors are stated systematically.With the permeation of underground water taken into consideration,an analytical geometry model is established which concerns the stability analysis of freeze and melt related loss of stability of earthen side slopes.By means of effective stress method,the stability coefficients of the loss of stability of earthen side slopes in earth frame and the mixture of earth and water are studied respectively.The identical stability coefficients are obtained. |

| Keywords: | seasonal frozen area loss of stability of side slope because of freeze and melt permeation of underground water effective stress method |
