Testing apparatus for simulating deep-displacement-initiated strata deformation coordination mechanism

Abstract

The invention relates to a testing apparatus for simulating a deep-displacement-initiated strata deformation coordination mechanism. The testing apparatus comprises a model box, a strata similar material, a molding fixed boundary mold, an air bag and measuring equipment. The model box is a main carrier of a model test; the strata similar material is used for simulating actual strata and combinations thereof; the molding fixed boundary mold is used for simulating the deep displacement boundary conditions of strata and can achieve the purpose of simulating different displacement boundary conditions through replacing molds with different shapes and parameters; the air bag is combined with the fixed boundary mold and is used for simulating the deep displacement of the strata and can preciselycontrol the air pressure in the air bag through an air valve to achieve the purpose of controlling displacement boundary parameters; and the measuring equipment achieves the precise measurement of a stratified displacement, a surface displacement, a soil pressure, a pore water pressure and the like. The testing apparatus for simulating the deep-displacement-initiated strata deformation coordination mechanism can be used for indoors simulating the influence of an underground deep continuous deformation process on an overlying strata deformation mechanism.

AI Technical Summary

Benefits of technology

This patented technology allows for accurate measurement of depths on various terrains without causing damage or affecting their functioning properly. By measuring these layers correctly, researchers are able to better model how they behave when there're changes over time due to factors like sedimentation from deeper levels. Additionally, this technology provides an efficient way to monitor dynamic behavior at both horizontal (subterranean) and vertical locations along tunnels.

Problems solved by technology

This patented technical problem addressed in this patents relates to testing how well an underground structure's movement affects its surroundings when it goes through tunneling operations or other types of construction activities such as road building projects that involve creation of holes within them. Existing methods require expensive equipment and may result in wasted material due to changing boundaries after each use. There currently exist several different ways to measure the effectiveness of ground movements without requiring costly replacements.
