Because of its irregular shape, it is inaccurate to calculate the bearing capacity of the A-shaped mat foundation by a conventional method, which may have potential safety hazards. In this paper, the vertical bearing capacity of the mat is obtained by using the equivalent calculation method (ECM) and the finite element method respectively, and compared with the centrifuge test results. A correction method based on the ECM is proposed. Influences of foundation dimensional parameters on the H, M and H-M combined bearing capacity are studied. Expressions of H-M failure envelopes related to the dimensional parameters are established. A new form of V-H-M envelope expression for mats is suggested according to the effect of vertical load on H-M capacity. The modified ECM and the V-H-M envelope proposed in the paper can be used to quickly evaluate the vertical bearing capacity of the A-shaped mat and its stability under coupling loads.
