本文从弹性力学基本原理和圆薄板微单元出发,将土工格室加筋体视为小挠度弹性薄板,考虑桩土变形及界面摩阻效应的影响,推导出三维轴对称条件下格室变形控制微分方程,采用Bessel复变函数构造三维条件下土工格室挠曲变形解析解答,并借鉴相关文献的边界条件进行了改进,继而得到计算土工格室网面下部桩土应力比、沉降及桩土差异沉降的计算公式,以期完善双向增强复合地基土工格室体变形计算方法。
In this paper, starting from the basic principle of elastic mechanics and the circular thin-plate micro-unit, the geocell reinforced body is regarded as a small-deflection elastic thin plate. Considering the effect of pile-soil deformation and interface frictional effect, Differential equations, the Bessel complex function is used to construct the solution of the geocell flexural deformation under three-dimensional conditions. The boundary conditions of the related literatures are used to improve the calculation results. Then the stress-strain ratio, settlement and pile- Differential settlement of the formula, in order to improve the bidirectional reinforced composite geocell body deformation calculation method.
