Abstract: Design of freezing method and construction monitoring in the construction of the connected aisle project in the tunnel was introduced.During the construction,the temperatures of salty water and frozen soil,the frost-heave force and the deformation of tunnel liner were surveyed.The variations of the surveyed results were examined.Information-construction had been assuranced.Good effects of freezing method were obtained in the project.
