Abstract: The shield launching section of Jianghai Road StationRailway Station section on No.1 line of Wuxi Metro is on a curve with 360 m radius. There are rivers, bridges and largediameter municipal pipelines above the shield launching head. There are many risks and great construction difficulties. Secant launching technology at primary section is adopted, so as to guarantee the successful launching and the safety of the river, bridges and pipelines, and to avoid overbreak. Horizontal freezing technology and consolidated section passing through technology by means of steam thawing combined with secant launching technology are used.
Key words: shield machine, soil consolidation, horizontal freezing method, secant launching, curve with small radius
