露天边坡与山坡复合体动态变形趋势的预测方法

Predicting method of dynamic deformation trend on combined body deformation of open-pit slope and hillside

在丘陵地区进行露天开采,露天边坡与山坡构成了复合变形体,致使2者变形相互作用,边坡滑移变形值大,由此影响边坡上各类设施的安全,且有些设施需要预先知道可能产生的变形值;为此,在地面监测结果动态分析的基础上,根据灰色理论方法,对后续变形的发展趋势进行了预测,经过后期实测结果的验证,效果较好。

Combined deformation body is constituted by open pit slope and hillside in hill area mining. Sliding deformation value is enlarged due to its interaction, measures safety is iidluenced and deformation value known is previous required for some measures.Therefore, according to grey theory continuing deformation value is predicted on basis of dynamic analysis of monitoring data,result is very well through later test of action data. Therefrore, basis is provided for safety of production measures and environment.
