| 摘 要： | 在厚冲积层下，地表沉陷与移动有自身的特点和变形规律，这些规律由上覆基岩和冲积层的综合影响所决定。在将冲积层视为随机介质，而将基岩看成是粘弹性基础上的粘弹性梁的基础上，建立了地表沉陷与变形预计的新方法及计算公式。通过实例分析，证明该方法比较符合实际。

| 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. |
