Tou Dao Gou Loose Accumulation Landslide Stability Evaluation And Their Development Trend Analysis

In recent years, landslide, collapse, landslides and other geological disasters occur frequently, safety threat to the lives of people, damage to the property security, seriously affected the sustainable development of social economy. With the change of the natural environment and human engineering activities, the landslide geological disaster frequency is very high, harm is very big.TouDao Gou loose accumulation compound is- medium-sized shallow soil landslide, it direct threat TouDao Gou and mine ore dressing workshop of lower road safe use, and have the possibility of debris flow in rain season, direct economic loss of more than one hundred million yuan, according to potential economic loss is incalculable. This to the local people’s lives and property caused serious threat. So for complex landslide TouDao Gou loose accumulation geological environment background, characteristics, formation conditions and stability are studied, and predicted its development trend and puts forward the governance plan, not only to the region’s people provide effective theory basis for disaster prevention and mitigation work, but also for other geological environment landslide studies provide some basis for similar regions.This paper TouDao Gou loose accumulation with compound landslide as the research object, and respectively analyzed the landslide geology environment background, characteristics, formation conditions, and based on this, the use of the method of qualitative analysis and quantitative analysis method, the compound TouDao Gou loose accumulat ion landslide stability is evaluated, according to the evaluation result of its development trend is forecasted, puts forward the control scheme. Mainly got the following results:(1) through the TouDao Gou loose accumulation compound the basic characteristics of the landslide, and study of physical and mechanical characteristics, deformation characteristics, analyzed the forming conditions of the landslide.(2) through the TouDao Gou loose accumulation compound landslide stability analysis: TouDao Gou loose accumulation compound landslide under natural conditions, the landslide is stable; Compound TouDao Gou loose accumulation landslide under natural condition + rain, more likely to lose stability of landslide, landslide is in a state of instability; TouDao Gou loose accumulation compound landslide under natural condition + earthquake, landslide, the possibility of losing stability, overall landslide in a state of flux.(3) through the analysis of the composite TouDao Gou loose accumulation landslide stability, forecasts its development trend, put forward three kinds of concrete. Finally, the fuzzy evaluation method on the optimal selection, the use of anti-slide pile + classification put drainage +section of the slope, vegetation restoration this solution for the optimal solution.
