Based on the engineering background of slope calamity control and restoration of ecological environment in Jianshan limestone mine,the paper makes an in-depth and systematic analysis.After years of mining,the great Jianshan limestone mine of Chaohu has formed a steep slope and destroyed the vegetation in the region,resulting in serious ecological environment damage.Therefore,it is very necessary to carry out slope disaster control and ecological rehabilitation in Jianshan.In addition to the reinforcement of the slope,there is a considerable part of the need for the environmental restoration of Jianshan,on the one hand to prevent the occurrence of slope instability,on the other hand,to prevent further damage to the surrounding environment of the big Jianshan.This paper mainly studies the factors of slope instability and the influence of reinforcement measures on the slope stability.By using the finite element software Midas to establish the slope model under the support of the slope,a comparative analysis is made.In the process of establishing the model,the dangerous slope is determined mainly by the study of the legal analysis of the stereographic projection,and one of the representative sections is selected for the study.First,determine the size of the slope and the horse track and the boundary range around the model,select the two supporting methods of retaining wall and anchor,and determine the mechanical parameters of the size and size of the material.Finally,the simulation results and the key slope stability coefficient are obtained.The comparison results show that the slope before reinforcement can not meet the requirements of the safety of the project.The slope after reinforcement is greatly reduced and the safety is greatly improved,whether it is from the slope displacement or the plastic zone in the slope.On the side of slope treatment,in the condition of maintaining the stability of the slope,combining the ecological environment around the slope,it mainly includes the layout of the sprinkler irrigation system.According to the location of the water source and the actual situation of the site construction,the slope maintenance irrigation system is set up to facilitate the maintenance and management of vegetation,and to ensure the normal growth of the plants;the construction of cultivated soil,The cultivated soil includes the planting soil of spraying mixed planting soil and the inner back fill of the horse road retaining wall.Because of the shortage of land resources,the construction of the loam soil should be based on the principle of economic and reasonable.Under the premise of guaranteeing the effect of the treatment,the land resources are saved and the construction cost is reduced.In accordance with the species of harmful insects and living habits on the ground and underground,the vegetation species,which are coordinated with the environment of the great Jianshan,adhere to the principle of prevention and comprehensive prevention and control.The methods of seed treatment,soil treatment and physical control and agricultural control are adopted in a comprehensive way.Comprehensive prevention and control measuresshould be taken to develop biological control.Through the treatment of the supporting structure,the hidden danger of the slope is completely eliminated,and the technology of spraying mixing and planting,retaining wall greening and so on is used to eliminate the visual pollution of the bare surface,so that the ecological environment of great Jianshan and the surrounding natural environment are coordinated.
