Along with urban construction's development, the side slope project becomes the key difficult project, the side slope existence hidden danger is more and more not allow to neglect, this request stable and makes the judgment and the safeguard safely in view of the side slope, thus in guaranteed that the person and under the property safety's premise, promotes the urban economic development and the facility construction.In order to study the evolutionary process which the side slope body distortion destroys, the side slope jitter's occurrence process and the criterion, in the foundation which the predecessor studies, this article designates the typical side slope, carries on the detailed geological prospecting and the corresponding rock mass field test and the related laboratory test, clarifies the side slope geological condition, the ground physical mechanics characteristic and the rock mass structural plane characteristic; Take the side slope classification and the rock mechanics characteristic research as the foundation, the use qualitative analytic method and the quantitative analysis law joint analysis side slope failure mechanism, forms the jointing the jointing crevasse growth characteristic to move toward the rose chart, uses the stereographic projection law to carry on the slope body stability appraisal to the structure characteristic; Carries on the simulation one by one through the general limit zero-method using the principle ground software to the side slope section plane, thus obtains the stable data; As well as carries on the finite element analysis method using the Midas/GTS software the formation computation achievement to do supplemented mutually analyzes and contrasts the research, the union engineering geology situation and the project numerical simulation analysis side slope stability.Under the finite element software Midas/GTS three dimensional side slope simulation, enables the side slope the overall deformation quantity, the biggest shearing strain distribution to obtain the very good analysis computation, its kinetic simulator is the side slope distortion process, the most dangerous situation unfolds one by one, the stability analysis result and the actual match case, the Midas/GTS software may take the side slope stability analyses the good method. As the Midas/GTS software which depends on may simulate any side slope form take the value analytic method, any small shape change, so long as performs precisely to the data, can simulate the formation, particularly the three dimensional side slope's simulation tallies with the side slope reality. Take the value analytic method as the Midas/GTS software which depends on the modelling process may consider when the side slope each influence factor, analyzes the question, it will study the side slope divides into the limited haploid, from these small units, regards as the entire gneiss's mechanics characteristic each small unit the sum total, thus obtains the entire rock mass mechanical balance relations. Each unit, may from factors and so on bulk specific gravity, elasticity coefficient, poisson's ratio, cohesive force, angle of friction describe, this can facilitate processing rock mass heterogeneous difficult problem.
