The invention provides a seismic isolation and water stop system at a sea area mining method tunnel deformation joint, which comprises a middle buried water stop belt and a seismic isolator, the middle buried water stop belt is arranged at a secondary lining deformation joint of a tunnel, one side of the inner surface of the secondary lining deformation joint of the tunnel is provided with an empty slot, and the inner surface of the empty slot is provided with a plurality of shock isolators. A plurality of vibration isolators are arranged in the empty groove in the circumferential direction of the tunnel deformation joint at intervals. The embedded type water stop belt comprises two embedded type rubber water stop belt bodies and a shape memory alloy piece, the shape memory alloy piece is bent towards the inner side of the tunnel to form a bypass structure used for drainage, and the two ends of the shape memory alloy piece are connected with embedded type rubber through clamp nails. By arranging the high-damp
