高陡矿山边坡稳定性动态分析及工程应用研究

露天开采形成的矿山边坡岩体的力学特性和稳定状态具有显著的动态特征,因此,传统的确定性分析方法难以获得可靠的稳定性分析结果。为此,结合边坡岩体的变形监测信息,提出了矿山边坡稳定性动态分析技术。为了进行边坡稳定性的动态分析,首先在边坡坡面布设一定数量的变形监测点,进行边坡变形监测。然后,根据矿山实际开采情况(坡高、坡角和地质构造),建立对应于当前开采状况的数值分析模型,并基于监测位移与计算位移之差最小为准则,进行等效边坡岩体参数的模式识别。最后,根据所获得的等效参数,进行当前边坡的稳定性评价或未来开采的稳定性预测。

Dynamic analysis method of stability of high and steep mine slopes stability and its application and study on a slope engineering

Because mechanics character of slope rock mass and stability condition in opencast mine have obvious dynamic character,so it is very difficult to got reliable analysis results by tradition method.Therefore,according to the information of deformation monitoring of slope rock mass in this paper,the technique of slope stability analysis was put forward.In order to analyze dynamically slope stability,some deformation monitoring dots were firstly laid on the slope face.Then,the numeric analysis model which corre...
