摘　　要：桥梁接线工程是桥梁发挥其交通功能必不可少的组成部分。同时,桥头接线方案受规划因素、现场条件、投资规模及环境等因素的制约,复杂性高,独立性强。现对于宽度超过100 m水系上的城市快速路和主干路,将桥头接线类型分为三种:互通式、分离式和平交式,并对三种桥头接线形式的适用场合做了研究。影响以上三种接线方案的主要影响因素有:规划因素、交通因素、道路因素和场地因素。通过定量描述和定性分析形成一套设计流程,旨在降低或避免设计的随意性、盲目性,通过设计要点和流程总结,为相似工程提供借鉴和参考。The connection engineering of bridge is an essential constituent part for a bridge playing its traffic function. Due to the conditionality of planning, field condition, investment scale, environment and the other factors, the complexity of bridgehead connection scheme is high and its independence is strong.For the urban expressways and arterial roads exceeding the 100 m-wide river system, the bridgehead connection is divided into three types of interchange, separation and at-grade crossing. The applicable occasions of the three bridgehead connection types are studied. The main factors affecting the above three connection schemes are the planning, traffic, road and site. A set of design process is formed by the quantitative description and qualitative analysis, which aims to reduce or avoid the randomness and blindness of the design. The summary of design essentials and design flow can provide the reference for the similar projects.
