The invention relates to a continuous loading rock mechanical device matched with X-optical mechanical scanning. An enhanced image system comprises a constant-pressure injector, a capillary tube and a contrast agent; a continuous control loading system comprises an experiment loading platform, a separation type hydraulic jack, a hydraulic control loading oil pump, a spoke pressure sensor, a digital display gauge and a computer; the experiment loading platform is formed by connecting a top seat, a bottom seat, a loading disc and a stress uniform distribution weight through a column rod; the separation type hydraulic jack is connected with the hydraulic control loading oil pump through an oil pipe; the oil pipe is provided with a flow meter; the capillary tube is connected with the constant-pressure injector and the experiment loading platform respectively; the contrast agent is injected into a test piece sample in the experiment loading platform through the constant-pressure injector and the capillary tube; the spoke pressure sensor is connected with the digital display gauge through an electric lead wire; and the digital display gauge is electrically connected with the computer. By virtue of the continuous loading rock mechanical device, data can be conveniently induced and analyzed; and the continuous loading rock mechanical device has a small volume and is convenient to move; and high-definition DR/CR image scanning pictures can be obtained, and quantitative analysis is convenient to realize.
