采动覆岩的叠层板—卸荷拱模型研究
|
摘要
针对地下矿物开采引起地表沉陷,并导致地表上建筑物、构筑物等严重破坏的灾害性现象,论述了研究离层注浆减缓地表下沉技术实施基础理论的必要性,提出叠层板—卸荷拱模型,基于叠层板、压力拱理论推导了岩板挠度的计算公式,建立了覆岩离层形成的力学判据,为离层注浆减缓地表下沉技术的实施提供理论依据。
Aiming at the surface subsidence and the havoc of buildings and structures on the surface caused by underground mining, this paper discussed the necessity of working over the basic theory of the technique implementation of reducing subsidence owing to abscission layer grouting, put forward a model of superimposed board-relief arch, deduced a calculation formula of the flexivity of rock board on the basis of the theory of superimposed board and pressure arch, and set up a mechanical criterion for the formation of abscission layer, all of these provide a theoretical basis for the technology implementation of the subsidence decrease by abscission layer grouting.
