摘要
依托某220 kV城区架空输电线路工程建设,介绍了重覆冰区双回路窄基钢管塔杆塔规划、设计过程及设计成果等情况,重点阐述了铁塔真型试验方案,并对构件应力及挂点位移作了对比分析,提出了窄基钢管塔的非线性效应、主斜材刚度比、次弯矩影响等方面的设计优化建议。
Based on the construction of a 220 kV urban overhead transmission line project,this paper introduces the tower planning,design process and design results of double circuit steel tube tower with narrow base in heavy icing area.This paper focuses on the test scheme of the full-scale model test,and makes a detailed comparative analysis of the member stress and hanging point displacement,and obtains the design optimization suggestions on the nonlinear effect,the stiffness ratio of main diagonal material and the secondary bending moment.
