摘　　要：结合广州地铁三号线天河客运站折返线隧道全断面超长水平冻结工程,基于相似理论,建立一套完整的物理模型试验系统,在保证冻结壁强度相似的前提下,重点对该隧道冻结暗挖过程中的冻胀和融沉位移场进行试验研究,为该工程的设计和施工提供科学的依据。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.
