| 摘 要： | 根据相似材料模拟实验结果，综合分析厚含水冲积层条件下采煤地表移动的主要特征，并且利用边界元法进行计算分析，从数学力学角度研究了厚含水冲积层条件下采煤的地层液化问题，解释了冲积层内和砂土层在动载荷下可能出现持续变形的移动机理，得出了一些很有意义的结论。

| Abstract: | Based on the results gotten from model experiment with similar material, the main features ofcoal mine surface moving under thick water-bearing alluvium condition are analysed comprehensively and calculated with limit element method; the strata liquidation under thick water-bearing alluvium condition is studied with mathematics and rnechanics; the moving mechanism of continuous de formation, appeared under dynamic load, of saturated sand-soil strata in alluvium is explained; and significant conclutions are came to. |
