极限平衡法与有限元法结合分析平阿高速公路高边坡稳定性

结合平安至阿岱高速公路高边坡工程实例，先用极限平衡法计算得出边坡的稳定安全系数，再用有限元法分析边坡的应力、应变和位移，这两种方法相结合既能反映边坡的稳定和变形之间的关系，又能用安全系数来评价边坡的稳定性。采用预应力锚索等加固，高边坡处于稳定状态。

Analysis on Stability of High Slope along Ping'an-Adai Highway by Combination of Limit Equilibrium Method and Finite Element Method

Combined with the case of high slope along Ping＇an-Adai Highway, the safety factor of the slope stability is calculated firstly by limit equilibrium method and then the stress, strain and displacement of the slope are analyzed by finite element method. The combination of two methods could reflect the relationship between slope stability and deformation, and the slope stability could be evaluated by the safety factor. The slope is reinforced by prestressed anchor cable so as to be stable.
