| 摘 要： | 利用ABAQUS提供的用户材料子程序UMAT的二次开发平台开发土石料的沈珠江双屈服面模型,并以一面板堆石坝为例,结合ABAQUS的“单元增加/去除”技术进行了坝体施工和水库蓄水的仿真分析.算例计算结果与用自编程序计算结果的比较表明,利用UMAT子程序开发的土石料沈珠江模型结合“单元增加/去除”技术进行土石坝施工仿真计算是可行的,计算结果合理可靠,且开发周期较自编程序大为缩短.

| Abstract: | The user material subroutine UMAT provided by the general software ABAQUS was used for programming for Shenzhujiang's double-yield surface model of earth rockfill materials.In combination with the element add/remove technique,a numerical simulation was performed for dam construction and reservoir impoundment in a case study of an earth rockfill dam.The result shows that the present method is feasible for numerical simulation of earth rockfill dam construction.The calculated result is reasonable,and the development cycle of the method is greatly reduced as compared with that of the user-compiled program.Therefore,the method is of certain reference value. |
