Gongbei tunnel on Zhuhai Link of Hong KongZhuhaiMacau Bridge is to be constructed by “Freezesealing Pipe Roof” (FSPR) method. FSPR, serving as a forepoling system, consists of three types of freezing pipes with special functions. Profiled enhancing freezingtube is aimed at minimizing the influence of the excavation disturbance and lining placement on the frozen soil. Based on the model experiment of FSPR, the effect of profiled enhancing freezingtube is presented. Conclusions drawn are as follows: 1) Using profiled enhancing freezingtube can weaken the thermal disturbance arising from the excavation and lining placement; 2) The safety of the excavation is improved because of the better frozen soil achieved by opening the profiled enhancing freezingtube in advance.
