摘要
介绍了一种新型真三轴巷道平面模型试验台的设计原理和技术特征。该试验台采用 6 个液压枕加载,最大施加载荷为 10 MPa,具有整体刚度好、柔性加载、受载均匀、伺服稳定等特点,能够实现效果较好的真三轴巷道模型试验。同时,介绍了与之配套的相似材料技术和有关巷道稳定性模拟试验的部分研究成果。
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.
