摘要
重力坝断面优化是一类常见优化问题,传统优化方法建模利用编程迭代优化,虽能得到优化序列,但对坝体整体的力学状态不能很好描述,同时模型离散化程度不高,因而计算精度也较低。利用有限元分析软件ANSYS对重力坝进行整体模拟,细化了单元,得到了各阶段的力学指标。使用ANSYS优化技术进行断面优化,取得了满意的效果。
Optimization of gravity dam section is a common optimization problem,the modeling that employs the traditional method is by means of programming iteration optimization. Although it can find optimum sequence, the mechanical state of the whole dam body cannot be completely described, and the dispersal degree of the model is low, as a result the precision of calculation isn＇t ideal. In this paper, gravity dam is simulated in whole by FEM analysis software-ANSYS, mechanical parameters in every phase are obtained by better FEM meshing. Satisfying effect in section optimization is obtained by optimum design of ANSYS.
