【摘要】 基于横向承载桩初参数方法的解,考虑地基土的层状特性和桩体的刚度变化,依据传递矩阵和子域法理论,以及子域边界处的连接条件,建立了横向承载桩与多层地基相互作用系统子域及体系的状态控制边值方程.根据系统的边值方程,可求得横向受荷桩的各种状态量及桩体侧面的土体抗力.为复杂情况下,横向承载桩的分析提供了一种简便、有效的计算方法.更多还原

【Abstract】 A status control boundary value method(SCBVM) is proposed for the analysis of a laterally loaded pile in multi-layered soils. According to the initial parameter solutions on the lateral pile in soil,as well as the transfer matrix method and the sub-domain method, a boundary value equation of the sub-domain is developed, and then, system status control boundary value equations are established for the interaction between the laterally loaded pile and the multi-layered soil by the continuous conditions between the sub-domains. The results of the final example given show the efficiency and convenience of the method.更多还原
