基于Kriging模型的挡风墙优化设计
Optimization of wind-break wall based on Kriging model
摘要
Abstract
The approximation technology based on Kiiging model was applied to the optimization design of the wind-break wall. Its key steps are as follows. Firstly, optimal Latin hypercube experimental design is well-proportioned, random and orthogonal in selecting the test sample points. Secondly, Kriging model is created by using the target value of the initial sample points. And the optimal solution is found combined with the optimization programming. In the design of the wind-break wail, variables are embankment and wind-break wall, and target value is overturn moment. At last, the best height of the wind-break wall is found through sequential quadratic programming. The analysis shows that this method can be well used in the design of the wind-break wall, the reasonable height of wind-break wall on different embankments can be obtained; the higher the embankment becomes, the more sensitivity between the overturn and the height of the wind-break wall becomes, and the lower the reasonable height of wind-break wall becomes.关键词
