| 摘 要： | 用弹性力学的有限单元法,研究了煤层开采所引起的地表移动变形的计算问题。在具体分析煤层开采后上覆岩层实际破坏特征的基础上,建立了岩体结构模型,编制了多功能有限元电算程序,提出了应用三次样条函数,根据层面节点位移求层面变形的计算方法,总結了表土层在岩移变形过程中的力学特征,通过对实际观测资料的拟合计算,验证了岩体结构模型的合理性和这种计算方法的有效性。

| Abstract: | This paper presents the study of strata movement due to coal mining and the computation of deformation using finite-element method of elastic mechanics on the basecs of the concrete analysis of the overlying strata failure characteristics, the author structures the rockmass model and draws up the multiple functional finite-element program, and put forward the computation method of strata plane deformation using the three times spline interplation function according to strata plane joint displancement.Through the fit calculation of ohservation data, the author tested and verified the rationality of the structure model of rockmass and the efficiency of the computation method, and summarized the mechanical features of the topsoil in strata movement and deformation |
