摘要
本文在将剪切位移法推广到塑性阶段从而得到桩周土非线性位移场解析表达式的基础上，与层状介质的有限层法和结构的有限元法联合运用，给出群桩与土和承台非线性共同作用分析的半解析半数值方法。算例与实例分析表明该方法简便有效，显示了广泛的应用前景。
In this paper,extending the shear displacement method to the plastic range,the analytical formulas of nonlinear shear displacement field in soils around pile are obtained. By use of these formulas combined with the finite layer method for layered soils and the finite element method of the structures,the semi-analytical and semi-numerical method for analyzing nonlinear inter action of pile group-soil-pile cap systems has been presented. The analysis of numerical examples and measured results shows that the suggested method is simple,convenient and efficient with good prospect of wide employment.
