| 摘 要： | 针对目前土质边坡地震稳定性评价还没有成熟可靠的标准，采用FLAC3D对土坡进行地震稳定性分析，得出：在土体强度参数中，摩擦角对土坡的稳定性影响最大。地震波传播方向平行于坡面时，比地震波传播方向与坡面相交时对土坡的危害要小得多。提出对土坡采用分级处理,多设置平台，更利于抗震。

| Abstract: | Soil slope is often performed in engineering projects such as road slope, the slope created by heaping mountain landscape, etc, but at present, the stability evaluation of soil slope under earthquake has not yet mature and reliable standard. Analysis of the stability of slopes under earthquake has been made by FLAC3D. Slopes using hierarchical processing and multi-platforms will be favorable to resisting earthquake. In the soil strength parameters, friction has the greatest impact on the stability of slopes. Hazards on the slopes are much smaller when seismic waves are parallel to the slope than when they intersect the slope. |
