The invention discloses a simulation method for gas-liquid mixed gap discharge characteristics. The method comprises the steps that a three-dimensional model of needle-plate gap discharge is constructed, an electrostatic module and a plasma module under AC-DC are selected to solve an electron and positive and negative ion convection diffusion equation, electric field and potential distribution of an air domain and a liquid domain is calculated, and the breakdown situation is observed. Gas and water are arranged in discharge areas between the rods and the plates, and the needle electrodes and the plate electrodes are made of aluminum; a tetrahedral mesh is selected as a mesh shape, a physical field control mesh is selected as a mesh division mode, and extremely fine division is selected as a fine degree; the whole process of gap discharge is simulated by referring to the generation and dissipation conditions of electrons in rod-plate gap discharge, and whether the discharge gap is broken down or not is detecte
