Abstract Boussinesq?s solution is adopted to calculate the additional stress at the tunnel axis caused by ground stack load. It is proposed that compared with the rigid body rotation，the shear dislocation plays a primary role for tunnel deformation modes. The formulas of the longitudinal deformation，dislocation displacement at segment joint，rotation angle at segment joint and shear force at segment joint of the tunnel are deduced according to the principle of minimum potential energy. The calculated results from the proposed method are compared with the data from the elastic foundation beam method and experiment measurement，which validates the proposed method. The effects of the rigid body rotation，shear dislocation，heap load，buried depth and the offset distance of the tunnel on the longitudinal deformation are studied. The deformation of the tunnel under ground stack load is dominated by the mode of shear dislocation. The larger the ratio coefficient j of the rigid body rotation is，the smaller the settlement of the tunnel is. The larger the load is，the larger the longitudinal settlement of the tunnel is，and the range of settlement changes little. The shallower the buried tunnel is，the larger the settlement of the tunnel is. The larger the offset distance is，the smaller the settlement of the tunnel is，and the horizontal displacement of the tunnel increases first and then decreases.

Key words： tunneling engineering shield tunnel rigid body rotation effect shearing dislocation ground stack load settlement
