混凝土面板堆石坝数值仿真分析

Numerical simulation analysis of concrete faced rock-fill dam

分析了面板堆石坝仿真计算中两种材料的本构模型的优缺点,根据混凝土面板堆石坝结构形式和坝体填筑材料物理性质复杂的特点,开发了FORTRAN语言编写的面板坝计算程序。该程序在面板分缝处理中采用分离缝模型的方法,符合实际面板之间的变形特性,并将该程序引进ANSYS商业软件中,充分利用商业软件的界面功能,提出了一种新的面板坝计算机数值模拟分析方法。该方法可以对混凝土面板堆石坝的整个施工过程和运行期进行二维和三维数值模拟计算和图形显示,结果形象、直观清楚。

Reviewed the various constitutive mode of concrete faced rock--fill dam, Basis on the complex physical characteristic of filled the material and the framework of dam, a method of computer is given, introduced into the program of the concrete face rock--fill dam calculation with FORTRAN language on the ANSYS software. It is used to simulate two and three--dimensional nonlinear computation and compute figure simulation in the construction procedure and operation period for the concrete tace rock fill dam, the result was intuitionist clarity.
