【Abstract】 Based on the nonlinear finite element, a new technique-arc-length method, is established for figuring out the critical load 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, Yong’an-Zhangping highway’s high embankment, it is indicated that the method is reliable and accessible.更多还原
