第 41 卷 增 1 岩石力学与工程学报 Vol. 41 2022 年 5 月 freezing model，controlling the development of the frozen wall boundary during the freezing process is the key to restraining the impact of frost heave and thaw settlement on the environment. Taking the freezing reinforcement project of Jiangpu Road Station of Shanghai Metro Line 18 as the background，model tests were designed and conducted based on similar theoretical，which on the development process of frozen wall boundary of steel pipe-frozen soil synergistic structure，analysing the influence law of steel pipe and circulating water on the boundary development，and conclusions were drawn as followed：The development of frozen soil can be inhibited by steel pipe set at the boundary of the frozen wall， which can also expand the temperature gradient at the boundary of the frozen wall，making the frozen wall more
