Abstract The fracture path of jointed rock masses has always been a hot and difficult problem in the fields of rock mechanics and engineering geology，and how to quickly and accurately calculate the fracture path of rock masses is of great significance in theory and engineering. In the present paper，a new method to determine the fracture path of jointed rock masses，taking the stress transmission in rock mass as fluid flow，is proposed based on flow field theory，and the feasibility of applying the flow field theory to the calculation of the stress field of jointed rock masses is verified based on the principle of equivalent analysis. The flow field analysis around the joint by using the theory of flow shows that there exists a flow region and a reverse flow area at the end of the joint，which verifies the stress concentration and the formation of tensile stress zone at end of the joint from the angle of the flow field. Finally，a method for determining the fracture path of rock masses is proposed according to the distribution of flow field concentrated zone and verified by the model test.
