A similar material simulation semi-flexible loading experimental device and its experimental method

Abstract

The invention discloses a similar material simulation semi-flexible loading experimental facility and an experimental method thereof. A loading device formed by a plurality of semi-flexible loading units is adopted on the basis of the prior art, the semi-flexible loading unit adopts a hexahedral structure form of which the bottom surface is only elastically deformed and other surfaces are made of rigid materials, and adopts a hydraulic oil transmission stress loading mode; connecting parts are arranged at two ends of a top beam and are fixed on a vertical column by bolts to realize detachable connection; a plurality of locating holes are formed in different height positions of the vertical column respectively, the top beam can be locked at the positions in different heights of the vertical column through the connecting parts by the bolts or hinge pins according to different experiment demands, and the problems that the sample model loading stress is non-uniform, the system error is caused, the adjustment is inconvenient and the operation is time-saving and labor-saving and the like are solved.

Description

technical field [0001] The invention relates to a simulation experiment device and an experiment method thereof, in particular to a similar material simulation semi-flexible loading experiment device and an experiment method thereof. Background technique [0002] Similar material simulation experiments are one of the main technical means for scientific and technological research in the fields of rock and soil, geology, and mining. The excavation of materials reproduces various mine pressure characteristics that occur during on-site mining, and is also one of the effective methods for geotechnical engineering to study on-site problems. [0003] With people's in-depth research in geotechnical, geological, mining and other fields, the requirements for research level and calculation accuracy are getting higher and higher, and higher requirements are put forward for the methods and equipment of similar material simulation experiments. [0004] In the prior art, the loading devic...

Problems solved by technology

[0005] However, the loading of heavy blocks can only be loaded with jumping loading pressure, and cannot be loaded accurately; in addition, due to the limited size of the test frame, the heavy blocks cannot be stacked too high; when stacking heavy blocks, the labor intensity is high, and the heavy blocks at high places are easy to slip, causing serious problems. Threat to the personal safety of experimenters

[0006] The problem with hydraulic jack loading is that when the loading surface of the model is deformed, the hydraulic jack cannot load the model continuously and stably

[0007] However, the loading of the liquid capsule cannot control the directionality of the pressure applied by the capsule and the uniformity of the force applied in the vertical downward direction, thereby affecting the accuracy and authenticity of the experimental results; tougher
