基于FLAC3D的贵州某高填方边坡稳定性分析

结合现场勘察资料，采用数值模拟方法，对贵州贞丰县某高填方边坡进行了稳定性分析。结果表明:在修建压实区和堆土区后，位移较大的区域主要集中在压实区和堆土区的表层，不会造成高填方边坡整体失稳；同时，对高填方区域开展了点安全系数计算分析，点安全系数较低的区域主要集中在压实区和堆土区表层，计算结果与位移分析结果吻合。

Stability Analysis of a High Fill Slope Based on FLAC3D in Guizhou

The stability of high fill slope is very important because of its high fill height and large fill amount. Combined with field survey data, the stability analysis The high fill slope in Zhenfeng County of Guizhou is carried out by numerical simulation method. The calculation results show that upon building the compaction area and soil stocking area, the area with larger displacement is mainly concentrated in the surface thereof, which will not cause the overall instability of the high fill slope; at the same time, point safety factor calculation analysis in high fill area is carried out. The areas with lower point safety factor are mainly concentrated in the surface of compaction area and soil stocking area the calculation results are consistent with the displacement analysis results.
