基于Matlab的桩锚支护结构优化设计

Optimal Design of Pile and Anchor Support Structure Based On Matlab

为解决存在于基坑工程设计中的经济性和安全性的矛盾,进行了桩锚支护结构的优化设计研究。选取适当的设计变量,以造价最低为目标函数,确定合理的约束条件,编写Matlab优化设计程序,将优化设计结果与原设计方案进行比较,验证了选取的设计变量大部分得以优化,可大大节约工程造价,得出合理的、可行的桩锚支护结构设计的参考结论。

In order to solve the contradictions of economy and safety,which exist in foundation pit engineering design,optimization design is studied on the pile anchor supporting structure,selecting the appropriate design variables,establishing the objective function which aims at the lowest cost,and determine reasonable constraint conditions,and then optimal design program is written by MATLAB language,Comparing the results of optimization design and the original design scheme,most of the design variables selected are optimized,which can greatly save the project cost,the reasonable and feasible reference conclusions can be found in the pile anchor supporting structure design.
