摘要

本研究利用 FEM3D 分析了新型互锁增强整体式土工格室（IEI geocell）加固地基的机理。研究了土体的垂直位移、水平位移和应力分布。此外，还研究了 IEI 土工格室条带的拉应力、摩擦力和接触力。研究发现，IEI 土工格室加固层可减少水平和垂直位移。IEI 土工格室的约束作用主要归因于填充材料与 IEI 土工格室壁之间的摩擦力。IEI 土工格室的刚度提供了张拉膜效应和更广泛的应力分布，使土壤地基的性能更好。

Analysis of Interlock-Enhanced Integral Geocell-Reinforced Foundation

This study analyzed the mechanism of a new interlock-enhanced integral geocell (IEI geocell)-reinforced foundation using FEM3D. The vertical displacement, horizontal displacement, and stress distribution in the soil were studied. The tensile stress, friction, and contact force of the IEI geocell strips were also investigated. The IEI geocell reinforcement layer was found to reduce the horizontal and vertical displacements. The confinement of the IEI geocell is mainly attributable to friction between the infill material and the IEI geocell wall. The stiffness of the IEI geocell offers a tensioned membrane effect and broader stress distribution, resulting in better performance of the soil foundation.
