Abstract：In order to study the deformation and failure mechanism of open-pit mine road slopes under the coupling effect of vehicle dynamic loads and groundwater,and provide reasonable deformation control techniques,this article systematically analyzes the geological conditions,influencing factors,and stability of road slopes using geological surveys,physical mechanics experiments and numerical simulation method.The results show that vehicle dynamic loads and groundwater decrease the stability of road slopes by 0.153 and 0.094,respectively.Under the coupling effect of the two,the slope stability coefficient decreases to 1.058,a decrease of 0.218.The softening of weak rock layers in slopes when exposed to water and the cumulative deformation caused by periodic vehicle dynamic loads are the fundamental reasons for the deformation of road slopes.The article makes the comprehensive comparison among the foot pressing method,anchor reinforcement,lane load reduction scheme based on the working space conditions,construction period and control effect.The final recommendation is a lane load reduction scheme of 2 m,which can improve the slope safety factor to 1.197.
