Abstract Freeze-sealing pipe roof method is applied in the Gongbei tunnel, which causes the ground surface uplift induced
by frost heave. A frost heaving prediction approach based on the coefficient of cold expansion is proposed to
simulate the ground deformation of the Gongbei tunnel. The coefficient of cold expansion in the model and the frost
heaving rate from the frost heave test under the hydration condition can achieve a good correspondence making
the calculation result closer to the actual engineering. The ground surface uplift along the lateral and longitudinal
direction are respectively analyzed and compared with the field measured data to… More >
