本科论文（设计）上海地铁1号线副线山泉路站基坑结构设计与施工设计.docx

摘要
本毕业设计主要包括三个部分,第一部分是上海地铁一号线副线山泉路站基坑结构设计;第二部分是上海地铁一号线副线山泉路站基坑施工组织设计;第三部分是专题部分,地铁基坑设计当中的土力学问题。
在第一部分基坑结构设计中,根据基坑所处的工程地质、水文地质条件和周边环境情况,通过施工方案的比选,确定采用明挖法施工,基坑维护结构采用地下连续墙,支撑结构采用钢支撑,并对其进行相应的地基承载力验算,土体抗隆起稳定性验算,抗渗验算,抗倾覆验算,整体圆弧滑动性验算,围护结构内力变形计算及强度验算。
第二部分是基坑施工组织设计,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,基坑围护结构施工及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。
第三部分是专题部分,内容是地铁基坑设计当中的土力学问题。结合相关的基坑土力学问题研究分析和工程实例,总结研究方法及其存在的问题。

ABSTRACT
This graduation design mainly includes three parts. The first part is a line of Shanghai metro line pair Springs Road station foundation pit structure design; the second part is a line of Shanghai metro line pair Springs Road station foundation pit anization design; the third part is the part of the topic, the subway foundation pit design of soil mechanics.
In the first part of the foundation structure design, according to the foundation pit engineering geological and hydrogeological conditions and the surrounding environment, through construction parison and selection, determine the use of open cut construction method, maintenance of foundation pit structure by underground continuous wall, supporting structure supported by the steel, and the of the corresponding foundation bearing capacity calculation, the excavation against heave stability checking, anti leakage checking, anti overturning checking, the whole arc sliding checking and internal force of retaining structure deformation calculation and strength check.
The second part is the foundation pit anization design, according to the construction method of the foundation pit and the foundation pit surrounding environment, before the construction preparation, construction site layout and retaining structure of foundation pit 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 thematic part, the content is the subway found
