基于支持向量机方法的抗滑桩优化设计及在边坡稳定性分析中的应用

为减少抗滑桩的受力分析工作量、提高抗滑桩的设计速度、快速优化其设计参数,基于支持向量机方法,采用有限元计算模型设计11组不同桩长、桩径的抗滑桩计算样本,建立抗滑桩优化设计数学模型,并应用于某河道断面设计中。结果表明,所建立的抗滑桩优化模型,可快速有效地搜索工程所需设计参数,为类似边坡抗滑桩设计提供参考依据。

Support vector machine （SVM）-based optimum design of anti-slide pile and its application to analysis of slope stability

In order to reduce the working amount for the stress analysis on anti-slide pile， speed up the design and quickly optimize the design parameters of it， a math-model for the optimum design of anti-slide pile is established with 11 groups of pile samples with different lengths and diameters for the calculation of anti-slide pile designed by means of the finite element calculation model based on the method of support vector machine， and then applied to the section design of a river channel. The result shows that the optimization model established herein can quickly and effectively search the design parameters necessary for the project， and thus can provide a reference basis for the design of the similar anti-slide pile for slope as well.
