摘要
以芜湖某工厂管线过河工程为工程背景,对管线上跨过河方案的桥梁选型进行分析比选,并通过建立空间模型对总体结构进行计算分析,论证了连续桁架桥的适用性和设计要点。该桥型具有显著的适用性和经济性,布置形式新颖、受力合理,可实现最优化设计,适宜推广使用,可为类似工程提供参考。
Based on the engineering background of a pipeline river-crossing project of a factory in Wuhu,the bridge types of pipeline across the river are analyzed and compared.The overall structure is calculated and analyzed by the establishment of a spatial model.The applicability and design essentials of continuous truss bridge are demonstrated.This type of bridge has the remarkable applicability and economy with the novel layout and reasonable stress,which can provide references for the similar projects.
