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 validate the model. The results
show that a good agreement between the frost heaving prediction model and the field measured data verifies the
rationality and applicability of the proposed model. The maximum uplift of the Gongbei tunnel appears at the
center of the model, gradually decreasing along with the lateral and longitudinal directions. The curve in the lateral
direction presents a normal distribution due to the influence of the constraint of two sides, while the one along the
lateral direction shapes like a parabola with the opening downward due to the temperature field distribution. The
model provides a reference for frost heaving engineering calculation.},
