The differentiation of model and prototype is only that there is a fixed proportion between the sequence structure and characteristic figure of the essential factors of the system, but the nature of controlling the system doesnt change. Setting up similar physical model is called similar physical emulated imitation from the point of emulation of the system. Through similar material simulation the horizontal and vertical stress of arch rock stratum i
