本研究建议的重点是确定钢筋螺栓的变形和强度行为,完全粘结到岩石与环氧树脂。这些树脂灌浆锚杆为钾盐矿中的巷道提供支撑,这些巷道可能在剪切和沿粘土层的扩张运动的组合下变形。由于剪切变形而在钢筋螺栓上引起的载荷随着剪切和扩张运动的大小而变化。由邻近岩体提供的剪切阻力也会影响已安装支架上的荷载。
英文摘要
This research proposal focuses on determining the deformation and strength behaviour of rebar bolts, fully bonded to the rock with epoxy resin. These resin grouted bolts provide support for drift backs in potash mines, which can deform under a combination of shear and dilational movement along clay seams. The load that is induced on rebar bolts due to shear deformation varies with the magnitude of both shear and dilational movement. The resistance to shearing, provided by the adjacent rock mass, also influences the load on the installed support.
