| 摘 要： | 利用摩尔-库仑理想弹塑性有限元方法，从水平位移着手，对高速公路软土路段新建-运营-加宽-运营等全过程进行模拟。在整个过程中，老路最大水平位移的大小及位置都在不停的发生变化，这在实际工程中值得注意。

| Abstract: | The horizontal displacement changes in the procedure of building-running-widening-running are simulated and analyzed with finite element method based on Mohr-Coulomb elastic-plastic soil behavior model. Conclusions show that the place and magnitude of the maximal horizontal displacement of old road is changed ceaselessly, and it should be paid more attention in practical engineering. |
