柔性搭板处治桥头跳车敏感因素分析

Analysis of Sensitive Factor for Flexible Approach Slab to Bridge End Vehicle Bump Treatment

应用PLAXIS非线性有限元软件,模拟了土工格室柔性搭板处治桥头跳车的施工及加载过程,通过对土工格室柔性搭板处治桥头跳车的影响因素的分析,提出了土工格室楔形柔性搭板的设计优化建议。

The construction and the loading process of using geocell reinforced flexible approach slab to treat vehicle bump at bridge end is simulated with PLAXIS nonlinear finite element software.Through the analysis of influence factors using geocell reinforced flexible approach slab to treat vehicle bump at bridge end,optimization design of geocell reinforced wedge-type flexible slab is proposed.
