摘要
抱杆和铁塔一样属于高耸结构,其高柔特性导致其对水平荷载非常敏感,针对淮上1 000k V特高压输电线路工程铁塔组立施工,选用座地双摇臂抱杆组立铁塔,并对铁塔与抱杆耦合系统的抗风性能进行研究。运用ANSYS软件对铁塔与抱杆耦合系统进行静力分析,明确铁塔与抱杆耦合系统在保证安全的情况下所能承受的最大风速,确定抱杆使用范围,从而为铁塔组立施工方案的编制提供依据。这种施工方法对临近带电体组塔施工、山区组塔施工等无法架设外拉线的塔位组塔施工有一定的借鉴意义。
Pole and tower belonging to the same high-rise structures, which led to its characteristic soft high load levels are very sensitive. For Huainan-Shanghai UHV transmission line project 1000KV tower erecting construction, the choice of the seat to the double pole rocker Assembling tower, and to study the coupling system tower and pole wind resistance. Using the ANSYS software to the tower and derrick coupling system for static analysis, determine the Tower and derrick coupling system maximum safe wind speed, determine the scope of the system used, for the tower construction plan formulation provides the basis. This method of construetion have a certain significance for the Assembling Tower Construction in the mountains and near the charged body where can not be set the wire rope in the outside of the tower.
