摘　　要：本文结合水泥土桩复合地基载荷试验， 现场量测了桩顶反力、桩间土反力， 分析了复合地基的桩土应力比、桩体应力集中系数、桩间土应力减小系数，并对复合地基中桩土分担荷载的特性进行了研究。The stress ratio between pile and earth in composite ground,concentration coefficient of pile stress,reducing coefficient of earth stress between piles are analyzed in association with loading test of the composite ground,field measured reaction of pile tip,reaction of earth between piles.The properties of shared loads between pile and earth in composite ground are also studied.
