QIU Pei-yun~1,YUE Feng-tian~1,YANG Guo-xiang~2,SUN Meng~2(1.School of Architecture & Civil Engineering,CUMT,Xuzhou 221008 P.R.China;2.Shanghai Tunnel Engineering CO.,LTD.Shanghai 200082 P.R.China)  
The application of a freezing method to construction of the connected aisle for Shanghai metro connected aisle project is introduced.This project is the first successful example for that the horizontal freezing method has been successfully adopted in the construction of heavy and long range connected aisle in China.This paper chiefly introduces the design of freezing method and construction monitoring.During the construction,the temperatures of frozen soil,the deformation of the ground surface,the expanding and releasing pressures in the soil were surveyed.The laws of the survey results were examined.The results can be used as reference for similar projects.
