| 中文摘要: |
| 在边坡稳定性分析与评价时应考虑基质吸力和支护方式的双重影响。鉴于传统边坡稳定性分析中存在的问题，应用Geo--Slope软件分析了考虑基质吸力影响的非饱和土边坡稳定性。揭示了基质吸力对边坡稳定性的影响程度，同时亦分析了潜在滑移面随基质吸力的开展状况和边坡安全系数对吸力内摩擦角的敏感度 |
| 英文摘要: |
| Dual effect of matrix suction and support model should be considered in the analysis and eval- uation of the stability of unsaturated soil slope. In view of the problems existing in the analysis of tra- ditional slope stability, the stability of unsaturated soil slope is analyzed considering the influence of matrix suction through Geo-slope software. The results reveal the contribution of matrix suction to the slope stability and the distribution of potential slide surface. The sensitivity of FOS （factor o{ safety） to the suction internal friction is also analyzed. |
