1、地铁一号线南湖路站实习报告————土木0907班庞亚军1208090722南湖路站1号线一期工程第六标段，位于南湖路与芙蓉中路的交界处，沿芙蓉中路南北呈一字型布置。南湖路站的基坑开挖方法采用的是明挖法。其优点为明挖法具有施工简单、快捷、经济、安全的优点，城市地下隧道式工程发展初期都把它作为首选的开挖技术。基坑开挖采用钢支撑施工。（1）钢支撑设计布置车站的基坑围护结构设置有内支撑，第一道支撑采用钢筋砼支撑，其余为钢支撑。（2）钢支撑架设工艺流程钢支撑架设工艺流程图otherstaffoftheCentre.Duringt

6、试拼装成完整单根钢支撑、围檩、牛腿验收合格后运至现场。保证钢支撑、围檩、牛腿质量符合设计要求。（5）钢支撑架设方法1）基坑开挖至支撑架设标高下0.5m的高度后，放出支撑位置。凿出围护桩上预埋件，焊接钢牛腿，在牛腿上焊制工字钢围檩。在钢工字围檩上焊制横撑固定配件。2）横撑先安装中间再安装两边，斜撑对角安装。用汽车吊将钢支撑吊放在围檩钢支撑固定配件上，锁定固定端。用两台100吨油压千斤顶在活动端按设计支撑轴力的1.05倍给钢支撑施加预加力，并采用特制定型钢楔锁定钢支撑。通过本次南湖路站的现场的观看，对明挖法和钢支撑有了一定
