摘要
本文应用有限元方法，编制了土工网处理桥头跳车力学模型分析程序，由计算出的土体应力及位移，分析出土与土工网相互作用机理及土工网加固土体的机理。本文的分析结果得到了实体工程实测结果及模型试验结果的验证，也为土工网的推广应用提供了理论依据。
Finite element program is developed to investigate the “bump” mechanics model at bridge approaches .After examining the character of stresses and displacements within the backfill behind bridge abutments,mechanism of geonets-soil interaction and soil stabilization is obtained.Results from this study have been checked by in situ measurement and model test.Theoretical foundation is provided to widely use geonets.
