摘要
两阶段变刚度复合桩基础新技术,其创新点在于端承型桩的变刚度机制的实现。现场测试通过布置沉降观测点、土压力盒以及轴力计等测试仪器采集现场数据,分别从沉降、土应力、桩顶反力、荷载分担比等方面分析两阶段变刚度复合桩基础的工作机理,以验证该工作机理在理论上的合理性。验证结果表明,两阶段变刚度复合桩基础的工作机理,在理论上有其可行性和合理性。
In this paper,the field test of the composite pile foundation is introduced,through the arrangement of settlement observation point,soil pressure box and axial force meter measuring instrument to collect field data. Respectively from the the settlement,soil stress,pile force and load sharing ratio analysis of composite pile foundation,the rationality of the working mechanism in theory and reference for engineering design were verfied.
