Abstract
The launching and arrival of shield are the key links in the whole shield construction,it is of practical significance to strengthen the research on relevant construction technology.Shield method is adopted in the construction between Xinjia-yuan East Station and Xinjiayuan Station of Tianjin Metro Line B1 in Binhai New Area,a reaction frame and a temporary in-stallation of negative loop pipe plates are used to provide reaction in the initial well at the end of the station.Through a series of preparation and technical measures,such as stratum reinforcement of end shaft,cutting of the retaining structure of the tun-nel door,sealing of the tunnel door,and dynamic adjustment of the initial driving parameters of the shield machine,etc.,the smooth initiation of shield in silty soil layer is ensured.关键词
