The invention relates to a modeling method and device for simulating a jointed rock mass roadway excavation test. The method comprises the steps of obtaining the basic information of a target roadway, and determining the basic information of a generalized model for constructing the target roadway in combination with test condition parameters, based on a BuckinghamPi similarity theorem and a control variable, determining a similarity relationship between the target roadway and the generalized model, obtaining raw materials for constructing a generalized model, corresponding proportion information and the number of required building blocks based on a Buckingham theory, a similarity relationship, basic information of a target roadway and basic information of the generalized model, thereby constructing the generalized model of the target roadway, and simulating an excavation test of the target roadway by utilizing the generalized model and a form removal device. According to the method, the problems of difficulty
