楔形双滑面稳定性动态分析及其在削坡治理中的应用──以神府-东胜和准格尔煤田露天采场斜坡为例

ANALYSIS OF DYNAMIC STABILITY OF WEDGE DOUBLE SLIP PLANE AND ITS APPLICATION TO HARNESS OF TRUNCATED SLOPE An Example from Slope Slope in Shenfu-Dongsheng and Junggar Coal Fields

摘要: 本文提出了可以连续地计算任何坡高不同坡角的双滑面楔形四面滑体的稳定系数, 以便求得某一稳定性系数的最优化坡角。本方法经神府-东胜及准格尔煤田采场斜坡验算, 得知两煤田采场斜坡还有较大的安全储备。

Abstract: In order to obtain an optimum slope angle corresponding to a stability factor, the stability factor of a wedge shaped four plane slip rockmass of double slipp planes and any slope height at different slope angle which can be forward caculated continuously is given in the paper. A test calculation of the stope slope in Shenfu Dongsheng and Jungar coal fields by using this method gives a more safety reserve of the slope.
