本科论文（设计）上海地铁1号线副线交通大学站基坑围护结构与施工组织设计.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1号线副线交通大学站基坑围护结构设计;第二部分是上海地铁1号线副线交通大学站基坑施工组织设计;第三部分是专题部分,交通荷载作用下软土地基长期沉降问题研究。
在第一部分基坑围护结构设计中,根据基坑穿越地层的工程地质、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,支撑体系采用钢结构,并对其进行相应的强度和稳定验算。
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,地下连续墙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。
第三部分是专题部分,针对交通荷载作用下软土地基长期沉降问题,通过用经验拟合法和有限差分软件相结合的方法,对隧道底部软土地基的长期沉降进行计算,总结出其长期沉降的规律。
关键词:基坑;地下连续墙;施工组织设计;围护结构;地基沉降
ABSTRACT
This graduation project consists of three parts, the first part of Shanghai Metro Line 1, sub-line Jiaotong University Station Foundation Pit design; the second part is the Shanghai Metro Line 1 line Jiaotong University Vice pit stop anization design; Third part of the thematic section, the traffic load under a long-term settlement of soft ground research questions.
In the first part of the foundation pit structure design, according to excavation works across strata geological, hydrogeological conditions and the surrounding environmental conditions, parison and selection of construction scheme, identified envelope using underground continuous wall, with steel support system, and its corresponding strength and stability in design.
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 thematic section, the content is under traffic load Soft Settlement of long-term problems. By fitting and finite difference bined with experience, simulation out of the tunnel, at the bottom of puting traffic loads in long-term settlement.
