The method comprises: performing three-dimensional modeling by using a real-time diameter D  t  of the blood vessel, a centerline length L of the blood vessel and a stenotic region of the blood vessel to form a three-dimensional blood vessel model having a stenotic lesion region (S01); performing an N-side mesh division along a circumferential surface of the three-dimensional blood vessel model to form a single-layer mesh model (S02); and performing a surface layering process on the single-layer mesh model to form a two-layer mesh model, thus obtaining a mathematical model of a blood vessel (S03). The present invention solves the problem in the prior art which lacks a three-dimensional blood vessel mesh model applicable to hydrodynamic analysis, thus meeting a need in the industry. As a blood vessel wall has a certain thickness and stenosis mainly occurs at an inner blood vessel wall, the mathematical model of a blood vessel is established as a two-layer mesh model having a certain thickness and comprising an inner-layer mesh model which has elasticity. The double-layer mesh model can be used to correct blood flow velocity, and thereby the real state of a blood vessel can be better approximated.
