大桥群桩基础设计方案优化分析

Optimization Analysis of Design Schemes of Large Bridge Pile Group Foundation

为优化大型桥梁群桩基础设计方案,采用有限元软件建立计算模型,模拟加载过程进行数值模拟分析。在选择不同设计方案的情况下,对大桥主墩群桩基础承载力进行计算,以基础承载力和安全系数等指标作为主要判定依据,对主要设计参数进行优化,得到了主墩群桩基础最优设计方案。

To optimize the design schemes of the pile group foundation of the large bridge,this paper established the calculation model by finite element software and conducted the numerical simulation by simulating the loading process.The bearing capacity of the pile group foundation of the main bridge pier was calculated in different design schemes.Based on the bearing capacity and safety factor,the main design parameters were optimized to obtain the optimum design scheme of the pile group foundation of the main pier.
