摘要
为了评价田湾核电站岩质高边坡的稳定性,应用有限差分强度折减法,对该核电站三、四期工程人工边坡的稳定性进行了计算分析,并与传统的极限平衡法的计算结果进行了对比。结果表明,由于有限差分强度折减法克服了极限平衡法未能考虑材料本构关系的不足,因而更能贴近实际模拟分析边坡的稳定状态,求得的边坡稳定系数更为合理。
In order to evaluate high rock slope stability of Tianwan Nuclear Power Plant （NPP）, by using the finite differential strehgth reduction method, in this paper the authors have calculated and analyzed the stability of the artificial slope stability of the 3rd and 4th phase of this project. Compared to the results with that of the traditional limit equilibrium method, it can be found that the finite differential strength reduction method can simulate the slope＇s stability better, also because that the constitutive relations of geotechnical materials is considered, as a result, thus stability coefficients obtained are more reasonable.
