本科论文（设计）上海地铁1号线副线富长路站基坑设计与施工.docx

摘要
本毕业设计主要包括三部分,第一部分是上海地铁1号线副线富长路站基坑设计;第二部分是上海地铁1号线副线富长路站基坑施工;第三部分是专题部分,高压固结后再冻结黏土的微观结构。
基坑设计部分,根据富长路站实际位置的工程地质、水文地质条件和周边环境情况,经方案比选,最终确定围护结构采用地下连续墙,支撑体系采用钢管支撑,并对其进行相应的强度稳定等验算。
基坑施工部分,根据基坑周边环境和施工方法,对施工进行准备工作,支护施工,场地布置,基坑开挖等设计,并编制了进度、质量、安全、环境保护等措施。
专题部分,通过SEM图像的研究,对比分析黏土与高压固结黏土和高压固结后再冻结黏土的微观结构,掌握黏土的物理力学性质以及高压固结和固结后再冻结黏土的特性,进而指导工程实践。

ABSTRACT
This graduation design mainly includes three part. The first part is the foundation pit design of the Fuchang Road Station of the Shanghai subsidiary Metro Line 1; The second part is construction design of the Fuchang Road Station of the Shanghai subsidiary Metro Line 1; The third part is special subject part which is the microstructure of frozen clay which underwent high pressure consolidation.
In the foundation pit design part, according to the engineering geology, hydrology geology conditions and the surrounding buildings of the actual foundation pit location, paring the construction schemes, confirm that foundation pit was constructed in accordance with diaphragm wall and steel support as support structure. It's carry on putation for strength and stability.
In the anization design part, according to the construction method and the environment circumstance of the foundation pit around, designing the construction preparative, the support structure constuction, the construction place arrange, and the foundation pit excavation. Besides, weaving to write the progress、quantity、safety and environmental protection management measure.
In the special subject part, mainly analyse the microstructure of the high pressure consolidated clay and the frozen clay after the consolidation through SEM images; in addition, master the mechanical behavior of clay and the characteristics of the high pressure consolidated clay and the frozen clay after the consolidation; furthermore, the engineering practice can be guide.
