铁路路堑,大坝坝基,煤炭、有色、黑色露天矿山均存在边坡稳定性分析计算问题。对新设计的露天矿,边坡稳定性分析的目的在于提供合理的阶段边坡角及最终边坡角,尤以后者最为重要,因其直接影响剥采比值及露天矿合理开采境界线位置。国内外大量统计资料说明,对大型露天矿,将最终边坡角提高1°,可减少数百万米~3的废石剥离量。对已投产的矿山,边坡稳定性分析是为寻求合理的边坡加固或整治措施提供依据。
Railway slopes, dam foundations, coal, non-ferrous and black open-pit mines all have slope stability analysis and calculation problems. For newly-designed open-pit mines, the purpose of the slope stability analysis is to provide a reasonable stage slope angle and final slope angle, especially since the latter is the most important because it directly affects the stripping ratio and the reasonable mining boundary line position of open pit mines. A large number of statistical data at home and abroad indicate that, for large-scale open-pit mines, the final slope angle will be increased by 1°, which can reduce the removal of waste stones from millions of meters to 3 tons. For the mines that have been put into production, the slope stability analysis is to provide a basis for seeking reasonable slope reinforcement or remediation measures.
