| 摘 要： | 以天津市慈海桥工程为背景,对新型斜拉桥与摩天轮组合结构体系开展研究以寻求更适合于慈海桥工程的合理的结构体系。在介绍慈海桥工程概况的基础上,对结构的组成和受力特点进行分析,指出组合结构主要通过轴力传递荷载的受力特点。提出两面索+桁架结构(结构体系A)和四面索+悬挂结构(结构体系B)两种结构体系,并从构成特点、受力和施工等方面对两种结构体系进行探讨分析与比较,得出四面索悬挂体系为更合理的结构体系。

| Abstract: | Taking Tianjin Cihai Bridge as the background,a structural system composed of new cable-stayed bridge with giant wheel is studied to find a more reasonable structural system for Cihai Bridge.On the basis of introducing the general situation of Cihai Bridge,the structural characteristic and load transferring trait are analyzed.It is pointed out that the loads are mainly borne by axial force system.Two structure systems are put forward,one is two-side cable truss structure system(structural system A),the other is four-side cable suspension structure system(structural system B).The two structural systems are studied and compared from the aspect of composition,structure and construction.And it comes to that the structural system B is a more rational one. |
