摘　　要：文章采用弹性半空间无限体内的Mindlin应力解及分层总和法，计算分析了柔性桩的桩土应力比随荷载水平、置换率、固化剂掺入量和桩长变化的规律，提出了以目标桩土应力比为控制因素的柔性桩复合地基优化设计方法。Mindlin formula in elastic medium and the layered summation for shallow foundation are adopted in this paper to analyse the variaton of stress ratio of pile-soil. replacement ratio, dosage and pile length. It is proved that we can well design the flexible pile composite ground by controlling the target stress ratio of pile-soil.
