摘要（英）：

The invention relates to the technical field of roadway surrounding rock failure physical simulation test and in particular relates to a roadway surrounding rock failure physical simulation testing apparatus and system. The roadway surrounding rock failure physical simulation testing apparatus comprises a loading device and flexible film bags, wherein the loading device comprises a box loading space used for placing test pieces; the flexible film bags are respectively arranged on the inner surface of the loading device; the flexible film bags allow oil to be injected into a pressure cavity inside; and the pressure cavity at least comprises a flexible surface used for contacting with the test pieces. According to the testing apparatus and method disclosed by the invention, the defects of the prior art can be effectively overcome, the friction force between the loading system and the test piece is eliminated, and the boundary effect generated in the experimental process is eliminated. Moreover, the whole apparatus disclosed by the invention has high stability, and liquid leakage is effectively avoided. Meanwhile, the device is ingenious in practical in structural design, low in manufacturing cost and favorable for popularization and application.
