摘 要
毕业设计主要包括三个部分，第一部分是佛山地铁XXX站深基坑围护结构设计；第二部分是佛山地铁XXX站深基坑施工组织设计；第三部分是专题部分，盾构施工预加固技术研究。
在第一部分深基坑围护结构设计中，根据XXX站深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深基坑的围护方案，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深基坑的抗渗、抗隆起和抗倾覆等验算。
第二部分的施工组织设计，根据深基坑围护方案、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、深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盾构施工中的预加固技术研究。针对工程施工中的地质条件和施工工况，总结了盾构施工中的土体预加固的技术措施和相关的参考资料，提出在盾构施工中土体预加固的技术措施。
关键词：深基坑； 地下连续墙； 施工组织； 支撑体系； 盾构预加固技术
The first part is the design of the deep foundation pit of the Foshan Metro XXX station. The second part is the construction design of the deep foundation pit of the Shenyang Metro XXX station. The third part is the special part, the shield construction pre-reinforcement Technical research.
In the first part of the deep foundation pit envelope design, according to XXX station deep foundation pit engineering geology, hydrogeological conditions and the surrounding environment, through the construction program comparison to determine the use of underground continuous wall as a deep foundation pit The support scheme is selected as the support, from the ground to the bottom of the pit in turn set up four steel pipe support, and the envelope structure and support the internal force calculation, the corresponding strength and the wall with the reinforcement check and deep foundation pit Infiltration, anti-uplift and anti-overturning.
The second part of the construction organization design, according to the deep foundation pit enclosure program, the construction method and the surrounding environment of the tunnel, the pre-construction work, the construction site layout, the envelope construction, the deep foundation pit excavation and support installation Design, and the preparation of the project schedule, the preparation of the corresponding quality, safety, environmental protection and other measures.
The third part of the topic is shield construction in the pre-reinforcement technology research. According to the geological conditions and construction conditions in engineering construction, the technical measures and relevant reference materials of soil pre - reinforcement in shield construction are summarized, and the technical measures of soil pre - reinforcement in shield construction are put forward.
Key words: deep foundation pit; underground continuous wall; construction organization; support system; shield pre-reinforcement technology
