有限变形下固-液耦合渗透固结问题的数值分析

NUMERICAL ANALYSIS ON SOLID-LIQUID COUPLILNG CONSOLIDATION PROBLEMS UNDER FINITE DEFORMATION

  • 摘要: 基于多相连续介质力学的理论,把土体抽象为叠合连续体,建立了有限变形下固-液耦合渗透固结问题的数学模型。基于IFEPG有限元自动生成系统,编制了有限变形和小变形的计算程序。通过实例对有限变形和小变形理论下的压力场、位移场和应力场等进行了分析。

     

    Abstract: Based on the theory of multi-phase continuous medium mechanics, a soil body is modeled as a piled continuous body. A Solid-Liquid coupling mathematical model for permeating consolidation problems under finite deformations is built up, which reflects Solid-Liquid mutual coupling. The finite element equations for Solid-Liquid biphasic medium coupling problems in finite deformations are built. Based on the automated generating system of the finite element of IFEPG, the corresponding computer programs are developed. The difference between finite deformation and small deformation in the cased pertinent to pressure field, displacement field and stress field are analyzed with different soil parameters.
