摘　　要：地铁车站出入口多采用浅埋暗挖法及明挖法施工。根据结构埋深,考虑经济效益,围护桩支护结构被越来越多的设计人员所选用。随着城市化进程的发展,地铁车站出入口选址极大地受地下管线、周边建(构)筑物的影响。对某地铁车站围护桩施工中遇到的管线、建筑物情况,以及在围护桩施工时采取的技术方案进行了研究,发现本工程采取的技术措施使围护桩收敛、水平位移、管线沉降控制均能较好地满足结构质量及管线沉降要求,以期为类似工程施工提供借鉴。The entrance and exit of subway stations are often constructed by shallow mining method and cut-and-cover method.Based on the depth of the structure and economic benefits,retaining piles are selected by a growing number of designers.With the development of urbanization,the site selection of entrances and exits is greatly affected by underground pipelines,surrounding buildings and structures.The article studied the technical solution of retaining piles,which was based on the situation of pipelines and buildings during the construction.the results show that the technical measures taken in this project can effectively meet the structural quality,pipelines settlement,the convergence and horizontal displacement of the retaining piles.The technical solution can provide some reference for construction of retaining piles.
