摘　　要：基于天然地基及单桩静载荷试验测得的p-s曲线,根据桩与桩间土的变形协调条件,推导了刚柔性基础条件下刚性桩复合地基桩土应力比的计算公式,通过与现场试验检测成果的对比分析,验证了该桩土应力比计算公式的合理性及实用性.Based on the measured p-s curve and the compatibility conditions of piles and the earth between piles, the author carries out the formula of pile-soil stress ratio of the composite ground with rigid pile under rigid foundation. Though comparison and analysis the measured results, the formula is considered to be reasonable and practical.
