Numerical Test Study on Ground Frost Heave Deformation Caused by Artificial Horizontal Ground Freezing Method

Bi, Gui Quan / Wang, Dong / Li, Ning

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.
