| Abstract: | With the background of the pipeline engineering of natural gas from Sichuan to the East in this paper,its main pipeline in Wuhan is adopting shield method to cross the Yangtze River.The dangerous case was when the shield arriving at the receive well,the tunnel inundated and the shield submerged in the soil body.And the freezing method applied in repairing project is presented on the key points of soil body strengthening.During the construction period,there is real time monitoring on frozen salt water temperature and frozen soil temperature with reasonable construction to solve the difficulties successfully. |
