摘要
针对整体滑动稳定安全系数满足规范要求的刚性桩复合地基路基仍然可能滑塌的事实,对刚性桩复合地基路基绕流滑动稳定分析开展了研究。基于对桩土作用力的研究,对桩土作用力进行了简化处理,提出了折减荷载法用于刚性桩复合地基绕流滑动稳定分析。工程实例表明刚性桩复合地基路基需要分析绕流滑动稳定性,折减荷载法简单实用。
The stability analysis of flow-slide of embankment on rigid-piles composite foundation was studied because the embankment might slide even if their safety factors of overall stability met the re- quirements of codes. A load reduction method for the stability analysis of flow-slide of embankment on rigid-piles composite foundation was proposed on the basis of analysis and simplified forces be- tween piles and soil. It was proven that the stability analysis of flow-slide should be taken into ac- count for embankment on rigid-piles composite foundation and the load reduction method is simple and practical.
