摘　　要：因建筑对造型的需要,大直径塔筒在工程设计中的应用日益广泛,而多个大直径塔筒相互连接出现在同一座塔中,更是较少见。大直径塔筒在设计上与常见的构架式塔架不同,如何确保相互相连的塔筒的局部稳定成为其设计的重点,而塔筒分片问题成为设计的难点。本文以大庆监测塔为例,介绍了此种特殊塔的结构设计应注意的构造设计,为今后类似的结构设计提供可参考的依据。In response to the need of the architectural lectotype,large diameter steel tube is gradually used in the structural design of the towers.The tower with several large diameter steel tubes connected with each other was rarely seen in the large scale project before,of which the new structure form is different from the traditional lattice towers.The most important thing to the designer is how to ensure the local stability of the large diameter steel tube.Subdividing the steel tube is also a key issue.In this paper,the special design of this tower is introduced based on the Daqing monitoring tower.The study can provide help for the analogous structures.
