本科论文（设计）常州地铁一号线华山路站车站基坑围护结构设计与施工.doc

摘要 本毕业设计主要包括三个部分，第一部分是常州地铁一号线华山路站车站基坑设计；第二部分是常州地铁一号线华山路站基坑施工组织设计；第三部分专题部分：地表沉降水位沉降对表土段井壁的影响。 在第一部分地铁车站基坑设计中，根据华山路站基坑所处场地的工程地质、水文地质条件和周边环境情况，通过施工方案的比选，确定围护结构采用地下连续墙，支撑结构采用混凝土支撑与钢支撑，并对其进行相应的强度、内力变形、承载力、抗渗、抗隆起、抗滑移、支撑内力变形验算。 第二部分是车站基坑施工组织设计，根据基坑施工方法和基坑周边的环境情况，对施工前准备工作，施工场地布置，围护结构施工与基坑开挖等进行设计，并编制了工程进度计划，编写了相应的质量、安全、环境保护等措施。 第三部分是专题，地表沉降、水位沉降对表土段井壁的影响，结合国内外专家的研究，确定地表沉降水位沉降产生的附加力是引起井壁破裂的一个主要原因。 关键词：基坑；地下连续墙；施工组织；水位沉降 ；竖直附加力；自动补水法；地面注浆 ABSTRACT Graduation design mainly includes three parts, the first part about the Changzhou metro line a Huashan Road station foundation pit enclosure structure design; second part about the Changzhou subway station foundation pit construction organization design; the third part about the special part, content for the tunnel connection channel structure health monitoring technology research. In the first part of foundation pit of subway station design, according to the Huashan Road Station Foundation Pit at the site engineering geological and hydrogeological conditions and the surrounding environment, through construction scheme selection, determine the retaining structure of the underground continuous wall, supporting structure with steel and concrete support support, and the of strength and stress in the corresponding deformation, bearing capacity, anti permeability, anti uplift, anti slip, support internal force deformation calculation. The second part is the station foundation pit construction organization design, according to the construction method of the foundation pit and the foundation pit surrounding environment, before the construction preparation, construction site layout and envelope structure construction and excavation design, and the preparation of the project schedule, the preparation of the corresponding quality, safety, environmental protection and other measures. The third part is the special subject, surface subsidence, water level settlement of surface borehole effect, combined with the study of domestic and foreign exp
