Dahong Mountain Iron Ore NO.1 Landslide Stability Evaluation And Governance Programme Design

Dahong mountain iron ore No.1 landslide lies at Dahong mountain iron ore 720 m mining industry venues platform northeast. This landslide position is important, there nearby has the important mine facility. In recent years the landslide border unceasingly expanded, the threat mine total property amounted to 48, 000, 000 Yuan, in order to guarantee nearby the landslide to construct, the construction security, urgently needed to carry on the reconnaissance and the government to this landslide. The stability of the landslide and Prevention study has important practical and theoretical significance.In this paper, date from investigates predecessor's material and research area related engineering geology material obtaining. Mainly is the terrain landform, the formation lithology, the geologic structure and the meteorological hydrology and so on, then carries on the engineering geology reconnaissance. According to landslides in the morphological characteristics , material composition , structural characteristics and the characteristics of deformation and failure to identify landslide sliding surface. By analyzing the causes of landslides mechanism, thereby stability evaluation, concluded that stability, the design and construction landslide governance programme design.The landslide borders quite clear that the middle-layer and medium-sized projects Landslide. The landside mass material ingredient mainly for fourth is the weathering product slope brown clay including the angle gravel, the crushed stone and the strong decency mudstone, the slate, skids the belt material ingredient mainly for the iron grey clay. The landslide formation aspects and so on terrain, lithological character, artificial activity is controlled, the precipitation function intensified the landslide development.Through geotechnical engineering investigation to determine the landslide slip surface for polyline, limit equilibrium method used in the transmission of thrust stability of the landslide. It stability coefficient values were less than 1 Fs landslides still is active, the need for landslide governing it.In view of the landslide leading suggestion factor, plans to use reduces slides with the government project measure which anti-slides unifies. Through resists the slippery retaining wall, anti-slippery project measures and so on pile, pre-stressed anchor cable carries on compared to chooses the proof, decided uses the pre-stressed anchor cable plan, the union anchor rod drifts net the slope protection, the biological slope protection measure as well as the surface, underground keeps off the draining water measure, and has carried on the executive project. Experience to test and engineering operations test to prove that the landslide governance programmes reliable.
