某桩筏基础细长桩单桩承载性能浅析

结合三根静载试验桩的试验数据,采用载荷传递法,利用迭代计算方法,编制计算程序对三根试验桩进行计算分析。通过对三根试验桩的计算数据与试验数据进行对比,获得两种不同类型的桩(嵌岩桩和非嵌岩桩)在载荷沉降变化趋势,桩身侧摩阻力与桩端阻力的分配,以及桩身轴力变化等方面的规律。

Study on Bearing Performance of A Single Pile by Load-Transfer Method

This paper theoretically analyses bearing performance of a single pile by load-transfer method, and then analyses three piles through calculation program by use of iterative calculation method. By contrasting calculation data to test data of the three piles, the law of changing trend of load and settlement, distribution of pile-lateral friction load and pile- end bearing resistance, and change of axis load in two kind of piles （piles socketed into rock and unsocketed into rock） could be achieved.
