摘　　要：随着城市建设水平不断提高,地上和地下基础设施分布日渐密集。在此背景下,城市轨道交通建设过程中出现了越来越多的近接工程。这是随着城市建设而出现的难以避免的问题,也是近年来地铁建设面对的难题之一。结合某城市100余处地铁近接工程进行分析,归纳不同形式近接工程的特点,指出不同服役结构在近接工程中的关注重点,分析不同施工方法中各类风险的存在及成因,最终依照案例总结出不同施工方法对应的常用施工控制措施。结合已有案例,解决近接工程的难题需要从方案预先设计、设备合理选型、强化控制措施、落实施工监测等方面进行思考和完善。Nowadays,the level of urban construction continues to improve,and the distribution of aboveground and underground infrastructure is becoming increasingly dense.In this context,more and more proximity projects appear in the construction process of urban rail transit.This is an unavoidable problem with urban construction,and it is also one of the difficult problems faced by subway construction in recent years.This paper analyzes more than one hundred subway access projects in a certain city,summarizes the characteristics of different forms of access projects,points out the focus of attention of different service structures in access projects,analyzes the existence and causes of various risks in different construction methods,and finally according to the cases,the commonly used construction control measures corresponding to different construction methods are summarized.Based on the existing cases,in order to solve the problem of access engineering,it is necessary to think and improve from the aspects of predesign of the scheme,reasonable selection of equipment,strengthening of control measures,and implementation of construction monitoring.
