The invention discloses a manufacturing method of a test model for simulating a stratified jointed rock mass similar material, relates to the field of geotechnical engineering, and aims to solve the problem that simulation is limited due to the fact that positions of discontinuous surfaces such as a layer surface and joints need to be preset in advance in an existing model structure. The method comprises the following specific steps of: determining mechanical parameters of simulation test similar materials according to mechanical parameters of a material to be simulated and a model test proportion, and determining the particle sizes of granular materials and the mix proportion of cementing materials according to the mechanical parameters of the similar material; laying steel balls layer bylayer and pouring a mixture according to a specific arrangement mode: according to the requirements of a model simulation rock stratum, a layer surface, a soft layer, a fault, a joint and the like, adopting a method of simultaneously pouring the granular materials and the cementing materials or firstly pouring the granular materials and then pouring the cementing materials to directly pour modeltest similar materials. The positions of the discontinuous surfaces such as bedding and joints can be directly set in the pouring process, and machining preset work does not need to be conducted in advance.
