  3. Abstract : incompatible element nh11 and hybrid stress element 18 were employed to analyze rock burst occurring in coal face 9108 of sanhejian coal mine. compared with the results from ansys, the two optimized fems can execute more accurate numerical simulation in the research of rock burst as well as other rock problems and lessen the errors from inaedquately meshing in huge calculations due to the limitation of labor and computer time. in addition, the criterion of averaged generalized stress rate was proposed and used to determine the site and moment of rock burst. the given conclusion is in accordance with the face of coal face 9108 very well

    文摘:利用優化非協調元和雜交元分析了三河尖礦沖擊礦壓,並與ansys程序的計算結果進行了比較.認為優化有限元在沖擊礦壓乃至巖石材料的數值模擬中能給出更為精確的結果,也可減小大型計算中由於人力、機時所限粗分網格產生的誤差.分析中,採用了廣義平均應力率準則來判斷沖擊點位置和沖擊時刻,所得結論與實際情況吻合
