为解决传统条分法在推移式滑坡的边坡稳定性分析计算中存在的不足，基于推移式滑坡的破坏机制，对 传统的条分法模型进行了改进，建立了一种简便的适应推移式滑坡的边坡稳定性分析模型，定义了其安全系数， 并推导出了相应的稳定性安全系数计算公式，开发出了推移式滑坡的边坡稳定性分析软件。该软件能准确识别推 移式滑坡形式、滑坡的最薄弱条块或条块群，工程师们可针对薄弱部位采取更合理、准确及经济的加固措施。通 过计算案例的对比与分析，考虑推移破坏模式下，其所得的安全系数通常较传统法小。因此，对于推移式滑坡在 评估和加固时，推荐采用推移式计算方法得到安全系数。
In order to solve the shortcoming of the traditional slice method in stability analysis and calculation of thrust-type landslide, based on landslide mechanism, the traditional slices mode was improved to establish a handy slope-stability-analysis model of thrust-type landslide. And a new safety factors was defined. The corresponding formula for calculating the stability safety factor was deduced. Moreover, the analysis computer program of thrust-type landslide was developed. The sliding form of thrust-type landslide and frail slices can be precisely distinguished by the program. Therefore, rational, accurate and economical measures can be taken to reinforce the slope. Comparing with traditional slice method, the safety factor of thrust-type landslide is usually smaller. The method is recommended to evaluate and reinforce the slope.
