Yunnan Slope Stability Analysis Of A Mine Crushing Station Research And Treatment Measures

With the rapid growth of our population and the rapid development of urban construction, as non-renewable resources, the land resources are increasingly difficult to meet the needs of people living and production. How to prevent landslides with the full use of limited land resources has become a problem which the modern society can not be ignored.While sliding piles itself has strong ability to apply a wide range of construction safety is simple, fast, small quantities, less investment environment and will not deteriorate further landslide geological conditions, can effectively verify and adjust design, etc. to make it more and more widespread concern in geotechnical engineering.In this thesis, Yunnan Hualian Zinc Indium Corporation Man Jiazhai stope crushing station slope stability and support measures for research as background, combined with the previous resulting in Slope Engineering research, cited a number of people in the research side slope engineering process used to some of the slope stability analysis methods, and slopes reinforced piles supporting research status. In the paper, the use of slope stability analysis of limit equilibrium analysis method to study the stability evaluation based on the results of slope reinforcement made specific control measures. Explore the design parameters piles against sliding pile soil arching effect is the choice of the numerical simulation method (FLAC3D method).The main contents of this paper can be summarized in the following four areas:1. A brief introduction to the main slope engineering slope stability analysis methods as well as some history of the development research status, piles supporting research the history, current situation and problems of soil arching theory as well as on some research status quo.2. Introduced the thesis research engineering background and major geological conditions, including engineering geology, meteorology and hydrology geological conditions, adverse geological and seismic effects. Meanwhile detailed overview of the slope engineering.3through established according to the actual situation of the slope FLAC3D numerical analysis model, when the slope reinforced with piles pile spacing when changing its cross-sectional dimensions and the pile of pile-soil arching effect against sliding impact analysis, both parameters have been changed when piles supporting effect ensued a series of changes and summed up this variation, in order to get useful conclusions on the actual project.4.By limiting equilibrium calculations carried out on the slope illustrates the necessity of supporting reinforcement, according to the results identified as supporting means piles and piles gives the main design parameters. Through the pile-soil interaction mechanism leads to the soil arching effect, on the basis of soil arching gives the maximum pile spacing calculation model formula.
