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。
Pile- soil stress ratio is one of the important factor which decides bearing capacity of composite foundation. Base on limit state of the beating 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.
