description The invention relates to the technical field of railway tunnel engineering construction, in particular to a structure and method for resisting floor heave deformation of a tunnel and a construction method.The structure comprises a pressure relief well, the pressure relief well comprises a cavity structure located in an inverted arch filling layer, the bottom of the pressure relief well penetrates through an inverted arch, and the top of the pressure relief well is located below a rail; the multiple pressure relief wells are arranged in the longitudinal direction of the tunnel. By adopting the structure, a certain space is reserved through the pressure relief well, a release area for tunnel floor heave deformation is provided, meanwhile, the contact area of a tunnel bottom structure and a rock mass is reduced, rock mass deformation pressure transmitted to the tunnel bottom structure is reduced, upward deformation of the rock mass is induced to develop towards the free face of the pressure relief well, and mean
