High fill reinforced embankment is a better construction plan of assuring engineering quality. Ensuring the stability of slope, the stability analysis for the High fill reinforced embankment are two important aspects in high slope design. This paper classed the motheds of slope stability analysis and founded the model of homogeneous earth slope on the base of Finite Element Method. Finite element method is a familiar method in settlement calculation of embankment, and the authenticity of soil model parameters is the guarantee of higher accurate results.Each factor's influence on the tensile stress of the geogrids,on method of disposal tensile, the stress and displacement distribution in the cross sections of embankments and the response of foundations were analyzed. Based on the nonlinear finite element,a new technique,arc-length method,is established for figuring out the critical load under bearing capacity and for solving the high embankment's stability. This paper gives the discussion of the application of arc-length and the analysis of the engineering stability in soil engineering .By calculating the safety factor of one engineering, it is indicated that the method is reliable and accessible. It can search for the slip surface of slope in all calculational field by optimized step fastly and exactly at random. It gets the exact result for avoiding treat with the question simply in other methods of slope stability analysis. Based on ANSYS-APDL language,the linear and nonlinear finite element method programs for static analysis of the High reinforced embankments are made in this paper. The model is simple and practical .The examples show that the solution is highly accurate and proved to be satisfactory. T...
