| Abstract: | A new type of triaxial system developed for roadway model test is reported. The main advantages of this new servo-controlled test system are the high stiffness and small size in frame. During tests,the model can be flexibly loaded by six flat jack in three mutually perpendicular directions with arbitrary loading ratios. The system is capable of testing specimens with 1 m in width,1 m in height and 0.2 m in thickness. The servo-controlled maximum pressure is 10 MPa. So the system is capable of performing advanced tests such as floor heave of roadways in deep mining. In addition,other relevant experimental techniques on roadway stability model tests and similar material simulation are also introduced. |
