Abstract:The traffic function of bridge is based on the connection project. The program of connection is complex and independent, which is restricted by four factors including planning, site conditions, investment scale and environment. This article applies to water system with a width of more than 100m and urban expressways and arterial roads. We have divided the bridge connection into three types: intercommunication, separation and level crossing, and studied the applicable occasions. The main influencing factors affecting the above connections are: planning factors, traffic factors, road factors and site factors. A set of design process was formed by the ways of quantitative description and qualitative analysis. The purpose of this paper is to avoid the randomness and blindness of design, and provides reference for similar projects in further.
