本科论文（设计）广州地铁3号线市桥站-番禺广场站区间隧道设计与施工.doc

摘 要 本毕业设计主要包括三个部分，第一部分是市桥站-番禺广场站区间隧道结构设计；第二部分是市桥站-番禺广场站区间隧道施工组织设计；第三部分是专题部分，地下混凝土结构分解性侵蚀及对策。 在第一部分区间隧道结构设计中，根据隧道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，确定采用盾构法施工，隧道衬砌结构采用复合衬砌，并对其进行相应的强度和抗浮验算。 第二部分是区间隧道施工组织设计，根据隧道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，隧道开挖与衬砌结构施工等进行设计，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，内容是地下混凝土结构分解性侵蚀及对策。本文将对国内外工程上出现的常见分解性侵蚀现象进行原理分析，并在此基础上研究地下混凝土结构分解性侵蚀的处理对策，最后通过一个工程实例，对地下工程有效应对分解性侵蚀危害提出基本建议。 关键词：地下环境；混凝土；分解性侵蚀；耐久性；结构强度 ABSTRACT This graduation design mainly includes four parts: the first part is Shiqiao station of Guangzhou metro line 3 ~ between Fanyu square station tunnel lining structure calculation; The second part is Shiqiao station of Guangzhou metro line 3 ~ between Fanyu square station construction organization design; The third part is the projects section, decomposition erosion of underground concrete structures and its countermeasures;The fourth part is the translation part. In the second part, according to the characteristics of the palisade solutions and support, the preparation work before construction, concrete construction plan, construction general layout and construction schedule and management measures for design, and write the corresponding quality, safety and civilized management measures. In the third part, from the first pile static load test, This paper will analyze the common decomposition erosion phenomena at home and abroad.Based on this, the Countermeasures of the decomposition erosion of underground concrete structures are studied. Finally, a practical engineering example is proposed to deal with the damage of the underground concrete structures. The fourth part is the translation segment: Complete Model of Corrosion-Degraded Cyclic Bond Performance in Reinforced Concrete.
