基于Geo-Studio的露天采场边坡稳定性研究
Slope Stability of Open-Pit Based on Geo-Studio
摘要
Abstract
This paper takes Shigang mining area of Zhuocheng Mining as the engineering background.Through the site investigation and mining status diagramselects,the most typical slope section is selected.The HH-Slope/W pro-fessional module in the simulation software Geo Studio is used to conduct limit equilibrium analysis on the slope sec-tion,the most dangerous slip plane positions and slope safety factors were obtained for two typical profiles under three different working conditions:normal mining,blasting vibration,and blasting vibration + seismic force cou-pling.The results show that:(1)When the Morgensen price method is used to calculate the side slopes of the east-ern and western mining areas,the safety factors under the coupling of blasting vibration and seismic force are 1.217 and 1.078,respectively,which meet the requirements of the specifications.The slope stability is relatively high,and the safety factor calculated by the former is slightly larger than that of the latter;(2)As the load of the working condition increases,the dangerous plane exhibits a behavior of expanding towards the deeper part,and the stability gradually extends towards the critical instability state.关键词
