元线电和电视发射塔属干高耸构筑物,其高度已达500米。人们要求建造更高的这类构筑物,但这会遇到许多技术上的困难,首先要保证其在外荷载作用下的稳定性。在塔桅结构中是用多层倾斜牵索体系来保证其稳定性的,当塔架较高时,牵索拉开很大,以致建造它需要很大的场地,这在城市中往往不太可能。塔架越紧凑,它所占的场地越小,但是它需要大量的钢材,因而限制了它的应用。
Yuanxian Electric and TV Towers are towering structures and their height has reached 500 meters. People are demanding to build higher such structures, but this will encounter many technical difficulties, first of all to ensure their stability under external loads. In the tower structure, a multi-layer inclined guyed system is used to ensure its stability. When the tower is high, the pulling rope is pulled up so much that it requires a lot of space, which is not always the case in cities. may. The more compact the tower, the smaller it occupies, but it requires a lot of steel, thus limiting its application.
