本科论文（设计）常州地铁常州北站站基坑围护结构设计和施工组织设计.doc

摘要
本毕业设计主要包括四个部分,第一部分是常州地铁一号线常州北站站基坑围护结构设计;第二部分是常州地铁一号线常州北站站基坑施工组织设计;第三部分是混凝土在硫酸盐环境中腐蚀产物的分析;第四部分是翻译部分,翻译文章为《混凝土混合料设计参数和干湿循环影响下的混凝土耐硫酸腐蚀特征》。
第一部分地铁车站基坑设计中,根据常州市地铁一号线常州北站站的勘察结果,选地连墙为常州北站站基坑的围护结构,钢支撑作为常州北站站基坑的支撑结构,进行相应的强度、内力变形、承载力、抗渗、抗隆起、抗滑移、支撑内力变形验算。
第二部分是常州北站站基坑施工组织设计,根据前期勘察资料和设计,常州北站站在施工提前做好哪些施工准备措施,在有限的施工场地内,如何合理有效使用场地,对围护结构和基坑开挖进行施工。
第三部分是混凝土在硫酸盐环境中的腐蚀产物分析。借助XRD、XRF及扫描电镜的手段分析腐蚀后的混凝土产物。
第四部分是翻译部分,翻译文章为《混凝土混合料设计参数和干湿循环影响下的混凝土耐硫酸腐蚀特征》。

ABSTRACT
This graduation design mainly includes four part, the first part is the structure design of the Changzhou North station foundation; The second part is the design of the Changzhou North station foundation anization design,The third part is special subject part which is the product of concrete corroded sulfate. The forth part translates an English article into Chinese article. The name of the paper is Effect of Mixture Design Parameters and Wetting-Drying Cycles on Resistance of Concrete to Sulfuric Acid Attack.
In the first part, according to the engineering geology, the hydrology geology conditions and environment circumstances of the foundation, paring the Construction schemes, confirm that the foundation used the open-cut method of construction, building envelope using diaphragm wall, the support structure of concrete and steel support bracing, and its corresponding strength, internal force deformation capacity, impermeability, anti-bump, anti-slip, brace force deformation analysis.
The second part is the foundation anization design, according to the excavation pattern and the environment circumstance of the foundation round, designing the construction preparative, the construction place arrange, foundation face advance sequences and tunnel linings construction.
The third part is the product of concrete corroded sulfate. According to XRD and SEM to analyze he product of concrete corroded sulfate.
The forth part translates an English article into Chinese article. The name of the paper is
