摘 要: 在厚沖積層下，地表沉陷與移動有自身的特點和變形規(guī)律，這些規(guī)律由上覆基巖和沖積層的綜合影響所決定。在將沖積層視為隨機介質(zhì)，而將基巖看成是粘彈性基礎上的粘彈性梁的基礎上，建立了地表沉陷與變形預計的新方法及計算公式。通過實例分析，證明該方法比較符合實際。

Abstract:In condition of mining under thick alluvial soil, the surface subsidence and deformations have distinctive characteristics and developing regularity which are decided by the bedrock and quaternary alluvial soil. Based on the alluvial soil regarded as random medium and the bedrock looked upon as viscoelasticity beam on the viscoelasticity foundation, the new method and calculation equations were set up for predicting and calculating surface subsidence and deformations. By means of example, the new method has been proved being in agreement well with the actual situation.
Key words: strata movement surface subsidence random medium theory
