中文摘要：
采动影响下采区上覆岩层将发生剧烈的调整，产生水平和垂直方向的位移。由于煤系岩层具有明显的分层性，这使得通过均匀介质或者松散体理论获得的岩层位移具有很大的局限性。建立了承受非均匀荷载的等效复合岩梁模型，并对上覆岩层的层间剪切滑移进行描述，且通过数值模拟和工程实例对模型进行了验证分析。结果表明，该模型是适合描述采区上覆岩层层间剪切滑移规律的。
英文摘要：
Under the mining disturbance the overlying strata will get a great adjustment; and displacements in the vertical and horizontal orientations occur. The characteristics of layers in coal geology overlying strata make the strata slipping displacement not reasonable which gained based on the homogeneous medium or loosening medium theory. So a complex rock beam model is set up to analyze the overlying strata shear slipping; and a numerical simulation for an engineering example is given to demonstrate the correctness of the model. The results show that the model is reasonable and feasible.
