摘　　要：通过混合桩型复合地基载荷试验测定了不同桩型及桩间土上的应力 ,分析了这种新型复合地基的桩土应力比的变化规律及破坏模式。通过与邻近的桩间土及单桩静载试验结果进行对比 ,对混合桩型复合地基中各类桩及桩间土的承载力折减系数及其影响因素进行了分析。The determination of the top reaction of different pile and the inter pile soil reaction are performed using the field plate load test in a composite foundation including mixed pile to study the variation of the pile soil stress ratio and the failure mode for this new type of composite foundation. By comparing with the in situ test data of the simple piles and the inter pile soil, this paper analyzes the reduction coefficient and the influence factor for the bearing capacity of each type of pile and the inter pile soil.
