Abstract

Abstract

A zigzag line tunnel in Tianhe Passenger Station of Guangzhou Subway is constructed by whole-section extra-long horizontal freezing method.One integrated model experiment system is established based on similar theory.Frost heaving and thawing settlement displacement of the tunnel is analyzed by model experiment on condition of ensuring freezing wall's similar intensity,which provides a scientific basis for design and construction of the project.
