The Study On The Slope Stability And Treatment Of A Chongqing's Chemical Plot

The research purpose of which the slope structure's distinguish, deformation destroy pattern and characteristic analysis, as well as the slope's deformation—destroy mechanism, is to build up the reasonable estimation of slope stability. It also does good to engineering design and construction.There are many kinds of slope stability analysis methods. The paper is based on a chemical industrial estate project in Chongqing. And select appropriate stability analysis methods, such as adopting polygon method (transfer coefficient method) to proceed slope stability analyzing estimation. At the foundation of the aspect, estimate all kinds of support system shape, applicable condition, the advantages and disadvantages of the supporting form. At last, from applicable condition of support systems, each part of slopes'stability properties, the degree of difficulty of construction of support systems, engineering impacts of support systems, and construction cost of support systems etc aspects, to make projects contrast research on typical part AB of support system, confirm finally best supporting scheme. Namely, part AB adopts balancing weight retaining wall, slope, lattice slope protection to supporting.The key points of this research are obtained as follows in the paper:(1) Slope's engineering geological condition of the chemical industrial estate project in Chongqing, is analyzed comprehensively by the numbers. Physical and mechanical characteristics of each part are expatiated in detail with this foundation.(2) Polygon method is utilized to analyze slope stability condition of each part, and general estimation of stability is also done. Parts AB and DF are the main filling slope, whose failure pattern is self arc failure or beeline failure. Cranny 1 of Part GH is almost tangent with slope, and cranny 2 and lay is out-dip structural plane which obliquity is quiet slow. Slope's stability is controlled by cranny 2. Cranny 2 of part HI and lay-plane tangent with slop. .Cranny 1 is out-dip structural plane. Rock slop'stability is controlled by cranny 1. After cut slope,rock slop will slip and break stability alone the cranny 1;On the peak of the part GH and HI.,there is a little of soil ,will happen soil slide.Height of filling is 2m to 10m,will break and slip alone the rock plane or failure self arc or beeline failure.(3) Three practical technology schemes for typical part AB are brought forward. The first is balancing weight retaining wall, slope, lattice slope protection to supporting.
