Abstract


Predecessors have made 3D limit equilibrium slope the results of the model, the traditional limit equilibrium model, such as the Bishop, Janbu, Spence have extended model has 3D. These extensions to the evaluation of slope stability model had a very good theoretical exploration, but the actual project work processes and technical means to restrict, not promote the use of these results. In this paper, the slope Dahongshan Plant as an example system the application of 3D model of the slope, including the purpose of reaching the finishing parameters that must be addressed,3D parameters of the formation of the division of 3D slope unit,3D most dangerous sliding surface, such as the establishment of and so on. In the elimination of 3D limit equilibrium method of slope of the problems of these applications developed on the basis of the corresponding software tools, in engineering a 3D limit equilibrium slope model. More traditional methods of work and results that will be 3D limit equilibrium slope model was applied to the actual works of far-reaching significance. Mainly include the following aspects of knowledge and results:(1) 3D limit equilibrium model is based on scientific theories, but it can not be calculated manually, but also through the realization of existing software. The use of 3D graphics technology, dynamic database technology, GIS technology, the development of new technologies and effective software systems to solve the mass parameters of the reserves and the matrix calculation, and reliable results.(2) 3D. stability analysis of factors affecting the need for a unified data platform. On the mechanical parameters and graphics data, the design of a unified program of data organization is conducive to unity in different engineering processes. According to DEM elevation data unit slope through gradient analysis of the main sliding direction, through the formation of 3D distribution of interpolation set of parameters, such as the mechanical process to form a complete set of data-processing program. A large amount of preparatory work to ensure data consistency. On this platform through the completion of the dynamic library of mechanical calculation of different models and improve the efficiency of the model and to facilitate the comparison, at the same time opening up the introduction of newer methods of technical preparation.(3) the election by completing a plant Dahongshan slope stability evaluation, the results of two-dimensional reference evaluation, the advantages are mainly the result of the advantages of graphics, as well as adjustment of the advantages of working conditions.
