摘要

    摘要
  • 摘要: 通过两组四桩多桩型刚性桩复合地基现场载荷试验,分析了多桩型刚性长短桩复合地基桩-土应力、荷载分担及其发展变化的工作性状;基于复合地基桩土应力及加载过程中深层土体水平位移实测结果,讨论刚性桩复合地基的应力扩散角理论;讨论了多桩型刚性长短桩复合地基承载力采用应力复合法计算参数的取值方法。相关成果将有助于复合地基特别是多桩型刚性桩复合地基的理论研究和工程应用,同时表明进一步进行多桩型复合地基现场试验研究与工程实测的必要性与紧迫性。
    Abstract: Based on two groups of four-pile field tests on a multi-type-pile composite foundation, the pile-soil stress, load sharing mechanism and its development character of the multi-type-pile composite foundation are analyzed. Based on the test results of horizontal displacement of deep soils in multi-type-pile stress and loading process, the theory of stress diffusion angle of the multi-type-pile composite foundation is discussed. The problems of stress compound method in calculating parameters for the bearing capacity of composite foundations are discussed. This work will contribute to the theoretical and technical development of the composite foundation. Moreover, to solve these problems needs effective tests and filed measurements in the future.
