| 摘 要： | 复合地基桩土应力比是决定复合地基承载性能的关键因素之一。本文基于复合地基承载力极限状态,推导了桩土应力比的理论计算公式,通过与现场试验检测成果的对比分析,验证了在极限状态工作条件下桩土应力比计算公式的合理性。

| Abstract: | Pile-soil stress ratio is one of the important factor which decides bearing capacity of composite foundation.Base on limit state of the bearing capacity,the authors carried out the formula of pile-soil stress ratio of the composite ground,as comparing and analyzing with the measured results,the formula is considered to be reasonable in the limit state. |
