夹江大桥非机动车道桥设计与分析

Design and Analysis of Non-motor Vehicle Lane Bridge of Jiajiang Bridge

依托南京夹江大桥非机动车道桥工程实例,对桥梁平面线位设计中所要考虑的因素进行分析与讨论;根据江心洲非机动车以电动自行车为主要车流的实际情况,对规范中关于非机动车最大限制纵坡进行了分析与研究;桥梁新老结构搭接遇到的反压支架进行论述,对设计和施工中需要注意的问题进行了探讨。

Based on the project instance of non-motor vehicle lane bridge of Jiajiang Bridge,the article analyzes and discusses the considered factors in the design of planar line of bridge.According to the actual situation that electric bicycles is the major traffic flow of non-motor vehicle,the article analyzes and researches the maximum limited longitudinal slope of non-motor vehicle required in the code.The article discusses the backpressure bracket occurred in lapping of the new and old bridge structures,and further discusses the problems for attention in the design and construction.
