Analysis of deformation mechanism of northwest slope in Buzhaoba Open-pit Mine based on multi-source monitoring
摘要
Abstract
Aiming at the deformation issue of the northwest slope in the Buzhaoba Open-pit Mine,this article reveals its instability mechanism based on a fusion analysis of multi-source monitoring data including total stations,rain gauges,and water level gauges,combined with numerical simulation.The results indicate that rainfall infiltration leads to the strength softening of the rock of northwest slope and soil mass and an increase in pore water pressure,thereby significantly weakening the anti-sliding resistance of the slope.Further inducing the northwest slope deformation,when the water level at the 1 190 m bench in the deformation zone rises from 1 156 m to 1 170 m,the safety factor of the slope drops sharply from 1.051 to 0.840.This study that groundwater is the primary controlling factor inducing the slip,and targeted prevention and control measures of slope deformation are proposed accordingly.关键词
