摘要
用有限元方法建立了复合地基刚性桩在水平荷载作用下的三维有限元模型,以桩的最大拉应变为目标函数,采用零阶优化法,定量地分析了各种因素影响下单桩复合地基的最优设计。
Utilizing finite element method the three-dimensional finite element model of composite foundation of rigid pile under horizontal load is built. Taking maximum strain as objective function and utilizing zero-order optimization the optimal design of composite foundation under the influences of various factors is quantitatively analyzed. Some valuable conclusions obtained.
