本科论文（设计）上海地铁一号线副线长安路站-基坑围护结构设计.doc

摘 要
 
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长安路站基坑围护结构设计;第二部分是上海长安路站基坑施工组织设计;第三部分是专题部分,工程降水对基坑支护结构土压力计算方法影响分析。
在第一部分基坑围护结构设计中,根据长安路站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,确定采用地下连续墙作为基坑的围护方案,支撑方案选为对撑,从地面至坑底依次设四道钢管支撑,并进行围护结构及支撑的内力计算、相应的强度和地连墙的配筋验算以及基坑的抗渗、抗隆起和抗倾覆等验算。 
第二部分的施工组织设计,根据基坑围护方案、施工方法和隧道周边的环境情况,对施工前准备工作,施工场地布置,围护结构施工、基坑开挖与支撑安装等进行设计,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。 
第三部分专题内容是工程降水对基坑支护结构土压力计算方法影响分析。介绍传统的土压力计算方法,以及最先进的土压力计算方法,重点介绍地下水对土压力计算的影响。
关键词:基坑; 地下连续墙; 施工组织; 支撑体系;
ABSTRACT
This graduation design mainly includes three part, the first part is the structure design of the Shanghai Metro Line Changan Road Station Pit; The second part is the design of the Shanghai Metro Line Road Station Pit anization,The third part is special subject part which is a preliminary study of the effect of Dewatering earth pressure calculation methods on structural.
The second part is Foundation pit anization design, according to the excavation pattern and the environment circumstance of the foundation pit around, designing the construction preparative, the construction place arrange, underground continuous wall construction and the foundation pit excavation. Estimating the work project, weaving to write the homologous quantity、safety、civilization management measure.
The third part is the special subject part. Its contents are a preliminary study of the effect of Dewatering earth pressure calculation methods on structural. The traditional calculation method of earth pressure, and the most advanced earth pressure calculation method is cited, focusing on the impact of groundwater on the earth pressure calculation.
Keyword: foundation pit; diaphragm wall; the anization design; retaining structure;
