Application of Displacement Mutation Criteria in Three-dimensional Analysis on Rock Slope in Left Bank of Qingda River

MA Yun-feng,SHI Gang(Institute of Geotechnical Engineering,Xi'an University of Technology,Xi'an,Shaanxi 710048,China)  
With the rapid development of the national economy,infrastructure investment and growth have reached unprecedented levels.In projects,there emerge a large number of the engineering problems of rock slope,which make the slope engineering analysis and evaluation appear to be all the more important.In this paper,the three-dimensional strength reduction is used to analyze the counterpart slope on the left bank of Qingda River,thus to obtain the relation-ship between the displacement and reduction factor.And then through the hyperbolic equation δ=(b+cK)/(1+aK) and the nonlinear least square method,the above results are fitted much better to obtain the safety factors of the slope.This method has been successfully applied to actual projects.
