【摘要】 对上海外环沉管隧道这一横断面规模居亚洲第一世界第三的管段结构制作施工技术作了介绍,并着重从大型沉管混凝土裂缝控制技术角度进行了理论和实践的针对性分析。其技术措施及分析方法对类似工程施工有借鉴作用。更多还原

【Abstract】 Introduced here is the manufa cture and construction technology of tube structure in Shanghai Outer Ri ng Im-mersed Tunnel, of which the tube cross-section is the 1 st in Asia and the 3 rd in world. Analysis in both theory and experi-ences is made on concrete crack control technology of large-sized immersed tunnel. The technical meas ures and analysis methods will give a reference to similar engineering constru ction.更多还原
