矿层开采后的地面沉陷和应力分析

Stress Analysis for Ground Subsidence Caused by Ore Seam or Coal Seam Mining

摘要: 本文交替使用半解析法中的有限层单元和三校柱单元，给出了矿层开采后的地面沉陷及应力分析的计算方法、公式和结果。

Abstract: in this paper, the finite stratiform elements and the triangular prism elements have been alternativelyused in the semi-analytic numerical method. The computational method, formulas and result of stress analysis forground subsidence caused by ore seam mining are presented.
