The invention discloses simulation test equipment and method for a super-load anchor pile cross beam counter-force device. In the equipment, the middle parts of two secondary beams are arranged on the top faces of the two ends of a main beam, and anchor pile caps are arranged on the top faces of the two ends of the secondary beams; two secondary pressure-bearing counter-force box girders are arranged on a test platform, and counter-force anchor pile caps are arranged on the bottom faces of the two ends of the secondary pressure-bearing counter-force box girders; four main pressure-bearing counter-force box girders are arranged side by side, and the two ends of the four main pressure-bearing counter-force box girders are arranged on the top faces of the middles of the two secondary pressure-bearing counter-force box girders; four-hole box girders are arranged at the two ends of the four main pressure-bearing counter-force box girders in a sleeving mode; an upper steel box cushion and a lower steel box cushion are arranged on the bottom face of the middle of the main beam and the top faces of the middles of the four main pressure-bearing counter-force box beams; six sets of jacks are arranged between the upper steel box cushion and the lower steel box cushion; a plurality of first twisted steel bars are welded between the anchor pile caps and the counter-force anchor pile caps; and a displacement sensor and a dial indicator are arranged on the main beam and the two secondary beams and used for detecting rigidity and deformation. According to the method, the main beam and the four main pressure-bearing counter-force box beams are subjected to graded loading and unloading through six sets of jacks, and whether the main beam and the secondary beams meet the requirement of the maximum load or not is judged.
