Summary:The invention belongs to the technical field of underground engineering, and particularly relates to a shield tunnel deformation quantity prediction method based on in-tunnel heaped loading, which comprises the following steps: acquiring soil parameters, shield tunnel related parameters and foundation pit excavation parameters; establishing a rectangular coordinate system by taking the excavation center of the foundation pit as the origin of a coordinate axis, the axis direction of the shield tunnel as the y axis, the x axis perpendicular to the y axis and the excavation depth direction of the foundation pit as the z axis; calculating the vertical displacement of the soil body at the axis of the shield tunnel, and calculating the upward additional load of the tunnel caused by the upheaval of the pit bottom of the foundation pit at the axis of the shield tunnel; calculating a soil body additional load caused by heaped load in the shield tunnel; calculating the total potential energy of shield tunnel deformatio
