大直径桩荷载传递规律的试验及理论研究
摘要:用室内直剪摩擦试验和压缩试验测定桩侧不同深度土层及桩端土层的荷载传递参数,根据桩土共同作用理论分析桩的荷载沉降关系及桩的荷载传递规律,为确定大直径桩的承载力提供了一种新的非破坏性的室内试验与理论分析相结合的方法,其分析结果与现场荷载试验结果完全吻合。
Abstract:Using direct shear friction and consolidation test to determine the load transfer parameters of soil surrounding the pile in different depth or beneath the pile tip, based on the theory of pile soil interaction, the relationship of load settlement and the law of load transfer have been studied. A new nondestructive method that combination with indoor test and theoretic analysis is presented. Comparision is made between the results obtained by the proposed method and the lo ad test data and close agreement has been found, thus verifying the reliability of the proposed method.
