description	The invention discloses a method for measuring and simulating mechanical parameters of a cemented weakly cemented rock. The method comprises the following steps: collecting a rock sample stress-strain curve and related mechanical parameters; establishing a standard uniaxial compression model and performing parameter correction to obtain a simulation parameter range; the method comprises the following steps: establishing a nanoindentation model, further adjusting simulation parameters within a simulation parameter range until a nanoindentation simulation curve is fitted with an experimental curve to obtain unique simulation parameters, then establishing a change curve of the simulation parameters along with the water content, and collecting a stress-strain curve and related mechanical parameters of the change curve. According to the change rule of the simulation parameters along with the water content, the simulation parameters are adjusted until a nanoindentation simulation curve is fitted with an experimenta
