摘要
有效桩长是影响复合地基沉降变形的一个主要因素。针对有效桩长的经验计算不能准确反映复合地基的沉降变形现象,采用弹性理论与大量数据结合的方法,得出一个考虑多种因素的有效桩长计算方法,进而给出有效桩长的计算公式,以此来预估复合地基的有效桩长。
Effective pile length is the critical element affecting the sedimentation of compound foundation. The failure of the experience calculation of effective pile length to respond to the sedimentation deformation of compound foundation is overcome by combining the theory of elastic with a large quantity of measure dates. The paper introduces a calculation method of effective pile length that consider variety factors, gives the calculation formula of effective pile length, and uses this formula of effective pile length to estimate the effective pile length of compound foundation.
