| 摘 要： | 通过建立双弹簧模型来模拟桥台对台背填土变形的影响，同时编制了相应的弹塑性动力有限元分析程序，分析研究了交通荷载反应作用下在不考虑桥台对填土的影响和考虑桥台对填土的影响，这2种工况下台背填土的变形特性，为工程实践提供了理论依据。

| Abstract: | Firstly,based on the two spring model proposed in order to simulate the soil deformation due to the bridge abutment under the automobile loadings ,a dynamic elasto plastic is proposed.Secondly,the deformation specialty of soil under two conditions: not considering and considering the soil deformation influenced by the bridge abutment, is studied.Then theoretical background is provided for engineering design and construction. |
