框架预应力锚杆支挡结构的分部优化设计策略

Local Optimal Design Strategies for Grillage Supporting Structure with Prestressed Anchor Bars

从结构优化设计理论的观点出发,提出了框架预应力锚杆支挡结构的分部优化设计策略,设计结果使得结构整体内力分布更均匀、设计更合理、材料更节省,并结合某黄土边坡框架预应力锚杆支挡结构进行了实证.其优化设计思想可为类似支挡结构的优化设计参考.

Based on the viewpoint of optimal design, the local strategies for grillage supporting structure with prestressed anchor bars are proposed. The results show the integral internal force distribution of the structure is more even, more rational and more economical in materials. This method can be used to optimize a grillage supporting structure with prestressed anchor bars on loess slopes. Can be used as reference for the similar supporting structures.
