Abstract

Abstract

Taking an interval of a utility tunnel over a ground fissure in Zhengzhou as the research object, numerical simulations were conducted to analyze the force and deformation of the ground and the utility tunnel in different settlements of the hangingwall of the ground crack. The analysis results showed that due to the large stiffness of the utility tunnel, when the settlement of the hangingwall was smaller, the ground over the utility tunnel heaved; with the increase in settlement, the heave of the ground dropped and the ground even settled, and the settlement and flexure of the utility tunnel increased. When the hangingwall settled, the tensile stress occurred in the top plate of the utility tunnel, and the maximum tensile stress generated at the center of the top plate of the utility tunnel. and the maximum value of tensile stress appears in the center of the top plate; simultaneously, the compressive stress generated in the bottom plate of the utility tunnel, and the maximum compressive stress appeared in the center of the bottom plate of the utility tunnel. With the increase in settlement of the hangingwall, both of the tensile and compressive stresses increased. When the hangingwall settled, the deformation in the direction of width of the utility tunnel was between 0.1 to 10 μm, which was tiny deformation. the deformation in the direction of axle of the utility tunnel was larger and the largest was in the direction of height, however, the deformation at each joint had not regularity.
