Abstract: Combined with the artificial horizontal soil freezing reinforcement construction for the arriving of shield machine in the northern end of the Metro station distribution law of horizontal soil wall thermal field was studied in artificial thawing condition. In this process ADINA finite element calculation software was applied to establish the artificial thawing model. Sensitivity of temperature of hot brine, circulation time of hot brine and distance between thawing pipes was analyzed. Calculation results indicated that raising temperature of brine, prolonging circulation time of brine and utilizing the shortest distance between thawing pipes could shorten the artificial thawing time of freezing wall. Furthermore, construction technical parameter and criteria of artificial thawing in arriving of shield machine horizontal freezing was proposed.
