Patent number: 11287356
Abstract: A variable angle loading testing machine is provided, which may include a bottom plate and a base fixedly connected to the bottom plate. A rock-sample accommodating cavity is formed in the base, and a rectangle-shaped sample is suitable for being placed into the rock-sample accommodating cavity. A side of the base is fixedly connected to two arc-shaped tension beams arranged in parallel, and a variable angle loading mechanism is slidably connected between the two arc-shaped tension beams. Through-holes are formed on the base, and an output end of the variable angle loading mechanism abuts against the rectangle-shaped sample through one of the through-holes. Loading and unloading of a stress with variable direction and magnitude under excavation disturbance can be simulated, which is of great significance for understanding mechanical behaviors of rock-soil mass under excavation disturbance.
