摘要
洞桩法作为复杂环境下地铁车站修建的常用施工方法,在地面交通繁忙、地下管线错综复杂且对地表沉降要求较高的工程中应用日益广泛,根据洞桩法需在无水环境下作业的施工特点,文章以西安地铁8号线丰和路地铁站洞桩法暗挖施工项目为背景,结合西安地铁车站工程施工降水经验,研究一种复杂环境下洞桩法地铁车站地面管井降水方法,并对该方法的工艺设计及监测数据进行分析研究,以期为同类项目提供借鉴指导。
As a common method of metro station construction in complex environment,PBA method is increasingly widely used in projects with heavy ground traffic and complex underground pipelines with high surface settlement requirements.According to the construction characteristics of the PBA method that needs to operate in anhydrous environments,this paper takes the PBA mining construction project of the Fenghe road metro station of Xi'an metro line 8 as the background,combined with the dewatering experience of the Xi'an metro project,A dewatering method of surface pipe well dewatering supplemented is studied,and the process design and monitoring data of this method are analyzed and studied in order to provide reference and guidance for similar projects.
