摘要
利用试验测得的 P-s曲线，确定沿桩身分布的各层土的力学指标。首先，选择一种较成熟的分析单桩沉降的方法，并利用所选择的分析方法，确定与指定沉降相应的荷载对各层土力学参数变化的敏感性；然后，利用此敏感性，调整各层土力学参数的值。如此反复进行，直至达到所要求的拟合精度。
The purpose of this paper is to determine the mechanic parameters of soils around pile with fiting P-s curve from loading test. Firstly, a method of analysing settlement of single pile must be selected, and the sensibility of load under specified settliment to variation of the parameters of soils must be determened with the selected method; then, based on the determined sensibility the parameters of soils are modified in order to fit the P-s curve. Finally, the required accuracy of fiting should be satisfied with iteration.
