Abstract: Aiming at frost heave problem existing in tunnel construction with artificial

horizontal ground freezing in coastal areas, this paper puts forward an equivalent load method

for frost heave simulation and a nonlinear deformation simulation method for soil around frost

wall. Employing the numerical test method, the designing parameters' influence on ground frost

heave is studied systematically. These parameters include depth of tunnel, frozen wall thickness,

excavation radius of tunnel and frost heaving ratio. Furthermore, some measures are proposed to

reduce ground frost heave. © (2013) Trans Tech Publications, Switzerland.
