地表下沉力学模型的建立及应用

A MECHANICAL MODEL OF SUBSIDENCE DUE TO MINING AND ITS APPLICATION

  • 摘要: 针对采动覆岩移动的规律,由弯曲下沉带的挠曲特性,应用薄板挠曲理论,建立地表下沉的最大值力学模型,预测覆岩离层未注浆和注浆条件下地表的下沉值.

     

    Abstract: Based on the law of the overburden movement, theflexible character of the bending zone and the correlation principlesin thin plate theory, a mechanial model of the maximum subsidence isfounded. The model can be used to forecast the subsidence value in thecondition of the layer separation being grouted or not grouted.
