非线性优化理论在抗滑桩设计中的应用

The Design Method and Application of Anti-slide Pile Based on the Nonlinear Theory

利用非线性优化理论,建立了抗滑桩优化设计模型。在现有抗滑桩优化设计研究的基础上,利用Matlab优化工具箱Fmincon函数,实现了抗滑桩设计的优化。云南省祥临二级公路的边坡抗滑桩优化设计结果表明:比原始的设计方案优化19.69%,大大地节省了设计成本。同时应用过程充分体现了Matlab优化工具箱的方便快捷等特点。

According to the nonlinear theory, the text eatables the formula about the optimized design of anti-slide pile and achieved the optimization design of it by the Fmincon function from the optimization box of Matlab. The anti-slide pile opti mization design results of the Xianglin 2nd grade road in Yunan province showed that： the cost can he reduced by 39.02% in comparison to the original project. In the meantime, the process analysis incarnated the facility of the optimization box of Matalab.
