Paper Title:
Study on the Simulated Testing on Repairing Drainage Pipe of Connecting Passage of Metro Tunnel with the Method of Liquid Nitrogen Freezing
  Abstract

The paper derives the similarity criterion aiming at the characteristics of repairing the drainage pipe with the method of the liquid nitrogen freezing in the connecting passage of metro tunnel, and establishes the simulated test system of the liquid nitrogen freezing based on the similarity theory. Through the simulated testing on repairing the drainage pipe with the method of liquid nitrogen freezing in the connecting passage of metro tunnel, we get the regulation of the temperature distribution of the freezing pipe wall, the regulation of the development of the freezing temperature field and the the frost heave displacement.The study instructs the repairing drainage pipe with the method of liquid nitrogen freezing in the connecting passage of metro tunnel, and promotes the development of the thoery of the liquid nitrogen freezing, also provides the reference and improvement for the engineering and study in the future.
