| 摘 要： | 应用PLAXIS非线性有限元软件,模拟了采用土工格室柔性搭板处理桥头跳车的施工及加载过程,综合分析了土工格室柔性搭板处理桥头跳车的作用性状。结果表明:采用土工格室柔性搭板处治桥后填土可将桥台路堤连接处台阶式沉降变为一段距离的缓坡式沉降,使桥台与路基达到了平稳过渡,能较好地解决桥头跳车问题,并提出了土工格室楔形柔性搭板的设计优化建议。

| Abstract: | Using PLAXIS nonlinear finite element software,the construction and the loading process of bumping at bridge-head by using flexible slab with geotechnical grid are simulated,and the function characters are also comprehensively analyzed.The results show that the filled soil after reinforced flexible slab with geotechnical grid can make the stepped settlement of joints of bridge-head embankment to a distance of the mild slope,and make the abutment and roadbed to smooth transition,so it can solve the problem o... |
