The utility model relates to a combined integrated anti-seepage heat-insulation plate with a channel frost heaving prevention function. The combined integrated anti-seepage heat-insulation plate comprises a plurality of combined plates which are optionally combined and connected with one another. Each combined plate comprises a middle flat plate structure and a peripheral connecting and interlocking structure, each middle flat plate structure comprises two anti-seepage layers and a heat-insulation plate arranged between the two anti-seepage layers; each peripheral connecting and interlocking structure comprises transverse beams and vertical beams, the transverse beams of each peripheral connecting and interlocking structure are provided with corner structures and are arranged on two opposite sides of the corresponding flat plate structure, the vertical beams of each peripheral connecting and interlocking structure are arranged on other two opposite sides of the corresponding flat plate structure, the inner side of each corner structure of each combined plate is in contact with the corresponding vertical beam of the corresponding adjacent combined plate in a butted manner, and the outer side of each corner structure of each combined plate is in contact with the outer side of the corresponding corner structure of the other corresponding adjacent combined plate in a butted manner. The combined integrated anti-seepage heat-insulation plate has the advantages that anti-seepage and heat-insulation functions are integrated, a combination technology is adopted, and accordingly the combined integrated anti-seepage heat-insulation plate has the anti-seepage function and the heat-insulation function; the combined integrated anti-seepage heat-insulation plate is of a combined structure, accordingly, the stability of connection among the plates can be guaranteed, and the anti-seepage reliability can be easily guaranteed for seams of the plates.
