部分斜拉桥结构对比分析

Structure Compacative Analysis of Partially Cable-Stayed Bridges

部分斜拉桥结构介于连续梁桥和斜拉桥之间,桥型结构兼具两者结构特性,且又具有自身的结构特点。本文对部分斜拉桥、连续梁桥和斜拉桥3种桥型结构进行计算对比分析,通过对内力和位移的分析比较,得出了部分斜拉桥结构的力学特性,为工程设计提供理论参考。

Partially cable-stayed bridge is a bridge structure style in between continuous beam bridge and cable-stayed bridge. This type of bridge possesses the characters of the two kinds of above bridges, and it also has oneself characters. Partially cable-stayed bridge, continuous beam bridge and cable-stayed bridge are calculated and compared in this paper, and the calculation results such as internal force and displacement are compared. The mechanics character of partially cable-stayed bridge is drawn out lastly. All of above provide the theory reference to engineering design.
