从高架油改电项目的立柱结构入手，在引入建模计算的基础上，通过成本核算、设计对比、强度校核，并借鉴成熟高压输变电路设计理念，确定并实施了最佳成本和结构的优化改造方案，经过一年半的使用和跟踪，高架油改电线路完全能够满足设计和码头工况要求。%Starting from the column structure of the overhead oil-to-electricity project , based on modeling calculation , the optimal reformation program for optimal cost and structure is determined and implemented through cost accounting , de-sign comparison , strength check , and reference to mature design concept of high-voltage transmission and transformation line.After application and tracking for a year and half , the overhead oil-to-electricity line can totally meet the design re-quirement and working condition requirement at wharf .
