Example Embodiment

[0015] Combine figure 1 and figure 2 , A flexible loading system for the three-dimensional physical simulation test bed of mine pressure, including a pressure providing device and a model; a liquid-filled bladder is arranged between the pressure providing device and the model, and the pressure provided by the pressure providing device is passed through the liquid-filled bladder Act on the surface of the model. The following focuses on the innovative part of the invention:

[0016] There are multiple liquid-filled bladders, three in the example, namely, liquid-filled bladders 1, 2, and 3. The liquid-filled bladders 1, 2, and 3 are arranged in sequence, and all the liquid-filled bladders are connected in sequence. The liquid-filled bladder is equipped with a liquid supply system 4. The liquid supply system 4 is equipped with a liquid supply pipe 401 and a liquid return pipe 402, and a flow meter 5 is installed on the liquid supply pipe 401 or the liquid return pipe 402. The pipelin...

Abstract

The invention discloses a flexible loading system for an underground pressure three dimensional physical simulation test platform, which comprises a pressure supply device and a model; the invention is characterized in that a liquid-filled bark pocket is arranged between the pressure supply device and the model, as well as pressure provided by the pressure supply device acts on the surface of the model by the liquid-filled bark pocket. The invention mainly has the advantages: in the loading process, load is forced on the surface of the model by the lower part of the liquid-filled bark pocket to cause the model to be uniformly pressed, thereby, the negative influence on a whole experiment caused by rigid loading in the prior art can be overcome, and the test effect is beneficial to being enhanced. In addition, a corresponding flow meter is arranged on a pipeline of a liquid supply system to lay a foundation for surface subsidence estimation and prediction.

Description

technical field [0001] The invention relates to a three-dimensional physical simulation test bed for mine pressure in stope, in particular to a loading system used in the three-dimensional physical simulation test bed for mine pressure in stope. Background technique [0002] At present, there are no more than two loading methods for the mine pressure physical simulation test bench in the laboratory: one is the force transmission block and manual jack; the other is the force transmission block and hydraulic jack. These two loading methods are both rigid loading in a macroscopic sense, and cannot objectively simulate the actual situation of rock formations. Since the rock stratum is in the stratum below a certain depth, it should be considered macroscopically that each layer of the rock stratum should have the same load. In the laboratory, due to the inconsistency in the laying of the model and the placement of the force transmission blocks, the applied load cannot act more un...
