To determine the appropriate soft foundation treatment for a river-crossing tunnel,freezing reinforcement design and technology were introduced based on the channel tunnel design and construction practice.Through finite element analysis and engineering practices,two rows of horizontal perforated freezing pipes were designed and installed on both sides of a passage for tunnel rein-forcement,which produced the thickness and strength of frozen crust that satisfied the design requirements.These information are valuable for guiding the design and construction of river-crossing tunnels in coastal areas.
