摘　　要：对于软土地基上填筑高土坡如果处理不当,高填土将会引起滑塌失稳等一系列工程灾害。采用Barron砂井固结理论和太沙基一维固结理论分析了软土地基在堆土荷载作用下的固结度。利用Bishop法和普通条分法分别计算了一次性堆载到最大高度和分级堆载到最大高度边坡的稳定性,并且考虑地基处理和固结的堆载地基稳定性,分析了不同排水工况下不同阶段土坡的稳定性,为工程施工操作具有有效的指导意义。For the high slope on soft ground, if not handled properly , it will cause instability and a series of engineering disasters . We use Barren sand drain consolidation theory and Terzaghi one-dimensional consolidation theory to analyze the degree of consolidation of soft soil under load. Using Bishop method and General slice method, we figured the stability of a one-time heap load to the maximum height and grading to the maximum height of heap load . And we also analyzed slope stabihty of the different drainage conditions at different stages, which works with a valid guide for action.
