本文仅对“抚顺型”地表下沉盆地的移动及变形进行了初步探讨。丛数理统计的观点出发,应用了岩石下沉过程与压密过程相似的假设,导出了下沉盆地的移动及变形的公式,它们是时间与空间的函数。进而,文章着重讨论下沉盆地稳定以后的地表移动与变形分布,变形的最大值及其出现的位置,以及地表点下沉的时间过程。同时,给出了根据地表移动观测结果求算地表变形各主要参数的方法,以及使地表变形计算简化所用的表格。最后引用了抚顺及阜新煤田10个地表下沉盆地的实测资料及抚顺煤田的5个地表点的下沉过程的资料,进行了理论与实测结果的对比,结果令人满意。
This paper only discusses the movement and deformation of “Fushun-type” surface subsidence basin. Based on the mathematical statistics, the hypothesis that the rock subsidence process is similar to the compaction process is applied, and the formulas of the movement and deformation of the subsidence basin are derived. They are a function of time and space. Furthermore, the paper focuses on the surface movement and deformation distribution, the maximum deformation and its location after the stabilization of the subsidence basin and the time course of the surface subsidence. At the same time, a method of calculating the main parameters of surface deformation based on the observation results of surface movement is given, and the table to simplify the calculation of surface deformation is given. Finally, the data of 10 surface subsidence basins in Fushun and Fuxin coalfields and the sinking process of 5 surface points in Fushun coalfield are cited. The results of the theoretical and experimental tests are compared with satisfactory results.
