多层地基中横向承载桩的边值分析法

Boundary value method for laterally loaded pile in multi-layered soil

根据横向承载桩初参数方法的解 ,考虑地基的层状特性和桩体的刚度变化 ,基于控制论理论方法 ,建立了状态控制方程边值分析方法。根据体系的状态边值控制方程 ,可依次求解得到各个子域的边界状态量 ,以及各个断面的状态量和桩体侧面的土体抗力。该方法计算简便 ,为各种支承条件、多层地基土层。

Based on solutions of the initial parameter method for laterally loaded pile, a new method (called status control boundary value method,SCBM)is presented, in which the layered characteristics of foundations and the rigidity changes of piles are considered, and the theoretical methods of cybernetics are introduced. This convenient method could be used for status analysis of laterally loaded pile with various boundary value conditions.
