Zusammenfassung:	The utility model provides a rock mass boring and shearing elastic modulus instrument mainly comprising a plug rod port (1), a loop bar (2), an upper disc cutter (3), a rubber sleeve (4) and a lower disc cutter (5), wherein the total structure is of a long cylinder. During tests, hole wall rock mass shearing tests under different positive stresses are carried out in different boring positions, and a destruction curve is drawn by utilizing a rock mass shearing destruction test structure under different positive stresses, so that a rock mass shearing resistant strength parameter is determined. The rock mass boring and shearing elastic modulus instrument is simple in structure, low in manufacturing cost, easy to use and maintain and simple and easy to repair.
