地下采矿诱发斜坡移动变形分析

地下采矿与滑坡的关系问题是近期社会关注的热点问题。基于对此问题已有研究的不足，以及随机介质理论在矿区地表移动与变形预测中的广泛应用，探索采用随机介质理论方法对地下采矿条件下坡体的移动变形规律进行研究。以重庆武隆鸡尾山崩滑体为研究对象，建立了坡体内两个地下采矿剖面的计算模型，并通过计算机编程辅助计算，对地下采矿条件下坡体的移动变形规律进行了分析，并对不同地下采矿工况分别进行了详细研究。计算表明，采矿诱发的坡体不均匀沉降加剧了鸡尾山坡体的移动下滑趋势，认为随机介质理论适用于地下采矿诱发的坡体移动变形分析。

ANALYSIS OF SLOPE MOVEMENT AND DEFORMATION INDUCED BY UNDERGROUND MINING AT JIWEISHAN,WULONG, CHONGQING

The causal link of underground mining and landslides is the focus of attention recently. Considering the limitations of previous undermining induced landslide research, the stochastic medium theory has been used widely in ground surface movement and deformation forecast in diggings. It tries to illuminate the slope movement and deformation principle resulted from underground mining with the stochastic medium theory. Taking Jiweishan landslide in Wulong, Chongqing for example, two models of undermining section in the slope are built. With computer aided calculation, the slope movement and deformation principles induced by undermining are analyzed. The different undermining conditions are also considered. The conclusion is as follow. The undermining-induced differential settlements aggravate the tendency to slip of the Jiweishan slope. The analysis indicates the stochastic medium theory is applicable to analyze slope movement and deformation principles induced by underground mining.
