摘　　要：通过有限元软件ABAQUS对长春某地铁车站出入口基坑进行了建模,使用其子程序DLOAD对动荷载进行数值模拟。详细分析了动载作用下管道的竖向变形比静载的有着大且不均匀的特点,随着载重、车速的增大,管道的竖向变形也呈线性增加。The base pit of the entrance and exit of a subway station in Changchun through the finite element software ABAQUS,using its sub-program DLOAD to simulate the dynamic load.The vertical deformation of the pipeline under the action of dynamic carriers has a larger and uneven characteristics than the static load.As the load and speed increase,the vertical deformation of the pipeline also increases linearly.

关 键 词：管道变形 数值模拟 动荷载 DLOAD
