The utility model discloses a ballastless track cutting structure and a ballastless track cutting system for an expansion deformation foundation. The cutting structure comprises an enlarged foundation, a deformation adjuster and a bearing device. The bearing device is arranged at the upper ends of the deformation adjusters, the deformation adjusters are fixedly connected with the top of the enlarged foundation, the deformation adjusters are arranged in the length direction of the rail at intervals, and the deformation adjusters are used for discovering deformation under the action of externalforce so as to allow the bearing device to move upwards or downwards. The cutting system adopts a cutting structure; the foundation is enlarged, so that large concentrated force transmitted by the deformation adjustor can be effectively diffused into the foundation; when the unfavorable deformation amount of the foundation exceeds the ballastless track requirement, the bearing device is driven bythe deformation adjuster t
