【摘要】 介绍了500kV新崖门大跨越输电塔的工程概况。给出了大跨越输电塔静力计算的原则,比较了大跨越输电塔有电梯井筒与无电梯井筒时的动力特性,分析了新崖门大跨越与原崖门大跨越之间的刚度差异,计算了大跨越输电塔的风振系数。最后,给出了大跨越输电塔的节点构造、地脚螺栓、休息平台以及走道等细部设计。本大跨越输电塔的设计方法可以作为同类大跨越输电塔的设计参考。更多还原

【Abstract】 The project situation of the new Yamen long-span transmission tower was introduced. The principle of the tower for static computation was presented. The dynamic characteristic of the tower with and without electric elevator were compared. The stiffness between the new and the old Yamen Transmission Tower are analyzed. The wind vibration coefficient of the tower was computed. Finally the detail design of structure joint, anchor bolt, rest platform and walkway for the tower were presented. The design can be provided a reference for design of similar long-span transmission tower.更多还原
