Abstract

The invention relates to a massive accumulation body boundary resistance experiment determination device and an experimental method. An after-calamity roadway is unstable and collapsed to cause the blockage of a rescue path, so that rescue is blocked, the time of rescue workers for arriving a resident area of rescuable personnel is delayed, and at the moment, how to safely and quickly pass becomes a key of realizing safe, quick and effective rescue after calamity. Pressure sensors are arranged on the side face of an experiment box, and are arranged in seven columns longitudinally and four pieces in each row; each pressure sensor is connected with a data acquisition instrument through a data cable; the data acquisition instrument is connected with a computer through the data cables. The massive accumulation body boundary resistance experiment determination device and the experimental method provided by the invention are applied in experiments of accumulation body boundary passive resistance and horizontal force between massives.

Description

[0001] Technical field: [0002] The invention relates to an experimental measuring device and a testing method for the boundary resistance of massive accumulation bodies. [0003] Background technique: [0004] After the disaster, the roadway became unstable and collapsed, resulting in the blockage of the rescue channel, which led to the obstruction of rescue and prolonged the time for rescuers to reach the area where the people waiting for rescue are stationed. key. [0005] Invention content: [0006] The object of the present invention is to provide an experimental measuring device and test method for the boundary resistance of massive piles, provide the judging conditions for whether the caving piles can fill the space, and deduce the height and boundary level of the caving piles The calculation formula of the resistance force and the lateral and longitudinal force at any point in the accumulation body gives the distribution curve of the vertical and horizontal force bet...
