description The invention discloses an unsymmetrial loading tunnel structure for applying prestress through a pilot tunnel and a construction method thereof. The unsymmetrial loading tunnel structure comprises atunnel and a frame beam fixed to the earth surface of a slope. A pre-stressed anchor cable is connected between the pilot tunnel of the tunnel and a frame beam. The construction method of the unsymmetrial loading tunnel structure comprises the steps that hole drilling is carried out in the pilot tunnel to be excavated from the earth surface of the unsymmetrial low side slope; the frame beam is constructed on the earth surface of the slope, the pilot tunnel is excavated, the pre-stressed anchor cable is placed in a drilled hole, and one end of the pre-stressed anchor cable is anchored on the frame beam; after prestress is applied to the pre-stressed anchor cable, the other end of the pre-stressed anchor cable is solidified on the wall of the pilot tunnel, and active reinforcing is carried out on the unsymmetrial lo
