1、摘 要 本科毕业设计说明书 南开区某地铁车站基坑支护（排桩） 及主体结构设计 A Subway Stations Foundation Pit Containment (Pile) and Structural Design of Nankai district 土木工程学院 2013 年 6 月 19 日 摘 要 基坑工程设计阶段的划分和文件组成取决于基坑内主体工程的性质、投资规 模、 建设计划等方面的要求， 一般分为总体方案设计施工和施工图设计两个阶段。 基坑总体方案设计目前多在主体工程设计完成后基坑施工前进行， 但为了使基坑 工程与主体工程之间能够更好地协调， 使基坑工程与主体工程的结合
2、更加经济合 理，许多大型基坑工程的总体方案设计在主体工程扩初设计中就着手进行，以利 于协调处理主体工程与基坑工程的相关问题。 天津地铁 2 号线是天津市快速轨道交通网中的东西骨干线， 西起西青区曹庄花 卉市场。线路全长 22.79km，其中地下线 21.42km，地面及过渡段 1.37km 本计算书包括深基坑围护和主体结构设计两大部分，主要内容有围护方案选 择、土压力计算、支撑内力计算、基坑稳定性验算、主体结构荷载确定、截面配 筋、降水计算和施工方案确定。 关键词：地铁车站；基坑支护；计算土压力；车站主体结构； ABSTRACT ABSTRACT The division of foundat

Overall de
4、sign foundation pit at present more than before after the completion of the foundation pit construction the major engineering design. But in order to make foundation pit engineering can better coordinate with the principal part of the project. Make the combination of foundation pit and the principal
5、 part of the project more economic and reasonable. Many large overall design of foundation pit engineering in the principal part of the project, for design is conducted, to facilitate coordination of dealing with the main body and foundation pit engineering related problems. Tianjin metro line 2 is
6、something in Tianjin rapid rail traffic network backbone line, west to xiqing district Cao Zhuang flower market. Line length 22.79 km, including line 21.42 km underground, ground and transition section 1.37 km. This calculation sheet includes two parts: the containment of the deep foundation pit and the design of the main structure. The main contents are the containment plan selection, soil pressure calculation, internal force calculation and foundation pit stability checking, determine the m
