| 摘 要： | 现有高填方路基的稳定性问题的分析均采用传统的饱和土强度理论,并没有考虑路基土体内由于地下水位下降等原因产生非饱和土层的情况,非饱和土中基质吸力对路基土体抗剪强度进而对其整体稳定性状产生的影响。采用非饱和土的强度理论推导了高填方路基整体稳定分析方法。

| Abstract: | The strength theory of saturated soil is used to analyze the stability of a high fill embankment,by which the unsaturated soil layer due to groundwater lowering in the embankment soil is not considered,the effect of shear strength and general stability in the embankment soil is caused by matrix suction in the unsaturated soil.The strength theory of unsaturated soil is used to derive a method for analyzing the integral stability of a high fill embankment. |

| Keywords: | unsaturated soil matrix suction integral stability high fill embankment |
