曹妃甸通岛路工程动静荷载变形数值分析

Numerical analysis of the deformation of caofeidian approach embankment under static and dynamic loads

应用二维有效应力法和EFESD计算程序分析了静力荷载、地震动力荷载和列车动荷载作用下稳定和变形情况。静力计算结果表明在路基稳定变形时,最大沉降约为80 cm,最大水平位移约为35 cm。动力计算表明,在地震荷载和列车荷载作用下路基均不会产生液化。地震荷载作用下,沉降约为35 cm,水平位移约为15 cm。列车荷载作用下,沉降约为120 cm,水平位移约为50 cm。

The deformation of the embankment under static load, earthquake load and train load was analyzed through 2D effect stress method and EFESD computation program. Under the static load, the maximum settlement is 80cm, and the maximum horizontal deformation is 35cm. The computation result showed that under dynamic load the foundation wound not liquefied. Under the earthquake load, the settlement is 35cm, the horizontal deformation is 15cm. Under the train load, the settlement is 120cm, the horizontal deformation is 50cm.
