Study on the Response Law of Deformation of Buildings by Harvesting

Abstract

Underground coal mining will cause violent deformation of the ground surface, forming a large area of subsidence area, building on coal mining subsidence area will have great safety risks, mastering the relevant laws of the deformation of the ground surface of the buildings and is the prerequisite to ensure the safety of the construction on the mining (movable) hollow area in the subsidence area. Taking the buildings in coal mining subsidence area as the research object, the means of combining 3D printing technology and similar material simulation are used, firstly, the printing materials and similar materials are screened, and the experimental model for researching the mechanism of building-foundation coupling is established, and through the experiments, the corresponding rules of the buildings and the deformation of the ground surface are summarized. Results show that: different types of buildings are affected by surface deformation differently, large buildings are more likely to be affected by quarrying, and large buildings are more likely to be affected by tilting deformation due to their stronger structural integrity.
