摘要
在厚冲积层条件下，冲积层和基岩作为两种不同的介质，其岩性和结构各不相同，在建立采动沉陷模型时，应当把它们作为两种不同的介质处理，合理地考虑冲积层和基岩对地表移动的综合影响。本文分别对冲积层和基层的移动特征作了理论上的探讨，并利用力学理论建立了复合岩层采动沉陷预计模型。
As the alluvium and the basement rock are two different medium, theirlithological characters and structure differ each other under the thick alluvium. Whenestablishing mining model, they should be processed as tWo different medium, and thecombined influence on subsidence caused by the movement of alluvium andbasement rock rationally considered. In this paper, the movement features of alluviumand basement rock are inquired on the theoretical plane, and the predicting model ofsubsidence established in terms of theory of mechanics.
