Abstract

The invention, which belongs to the technical field of engineering applied mechanics, particularly relates to a device and method for determining the acting force of an impact blocking belt during themovement process of loose particles. The device comprises an oblique circulating slot, an adjustable height bracket, a gate, a gate clamping piece, buffering blocking belts, a buffering blocking beltstorage box, a blocking belt height adjusting device, thin plates and fixed earth pressure sensors. The oblique circulating slot is formed in the adjustable height bracket; and an included angle is formed between the adjustable height bracket and the horizontal plane. The gate is arranged on the bottom surface of the oblique circulating slot; the buffering blocking belt storage box is installed at the lower part of the oblique circulating slot; the multiple buffering blocking belts can be arranged in the buffering blocking belt storage box; the thin plates are laid on the buffering blocking belts and the bottom surface of the oblique circulating slot. The fixed earth pressure sensors are arranged at the sides of the buffering blocking belts and the oblique circulating slot. According to the invention, the movement process of loose particles can be simulated and the impact force through the multiple buffering blocking belts and the changing process of the loose particles in the movement process are measured.

Description

technical field [0001] The invention belongs to the technical field of engineering applied mechanics, and in particular relates to a device and a method for measuring the force of impacting a barrier belt during the movement of loose particles. Background technique [0002] Debris flow is a common geological disaster with strong destructive ability, which usually poses a serious threat to people's life and property safety when it occurs. In order to effectively prevent and control debris flow disasters, the buffer barrier structure is usually widely used by people. Debris flow is a geological phenomenon of loose particle movement, which will have an impact on the buffer and barrier zone set along the bottom surface. The number and position of the buffer barriers will have a certain impact on the movement of the debris flow. At present, there is no systematic research on the influence of the buffer barrier along the bottom surface on the dynamic process of debris flow, and ...
