摘要
荷载传递法概念明确,能反映桩土体系的荷载-沉降主要工作机理,同时具有计算简单、实用性强的优点。根据桩侧和桩端土体的物理力学特性,利用荷载传递方法来确定桩的荷载-沉降关系,是近年来国内外学者广泛关注的问题,对工程界来说,研究这种方法也是很有必要的。分别从荷载传递函数类型、数值计算方法和参数选取及其优化等方面加以概括,总结了单桩荷载传递法近年来的最新进展。今后的工作中,应更加重视通过荷载传递机理分析和试验对比,得出较为实用的地区经验参数,指导设计和施工。
Load- transfer method can account for the working mechanism of the pile - soil system and the calculation is very simple. Using the load - transfer method to ascertain load- settlement curves is a very important method for researchers and engineers, based on the physical and mechanical characteristics of the soft on pile shaft and tip. New development of load - transfer method for settlement calculation of single pile is explained carefully, from the different load - transfer function, numerical analysis method and method to determine the calculation parameters and their optimization. Much attention should be paid to the comparison of experimentation and theoretical analysis with the locally experimential parameter used to designing and construction.
