Abstract: According to specificities for jointed rock mass, multiple sliding failure of a jointed rock mass is presented, due to accumulation of stress along bedded plane of rock mass and destruction of remnant intact rock bridges between bedded planes and joints. And rock triaxial serve testing system is used, through model test involving bedded planes and a set of joint normal to the bedded planes in rock mass, effects of properties of joints and confining pressure on multiple sliding failure are analyzed; the condition triggered multiple sliding failure and characteristic of failure plane is given, under the co-action of inclination of connective joints (bedded planes), interlocking conditions of critical joints, and confining pressure. At last, data are compared with predecessors’ones, and on the basis of it reliable results are given; and the results are hoped to supply guidelines for assessing probable modes of failure of a jointed rock mass for future practice.

Key words: jointed rock mass, multiple sliding failure, model test, connectivity
