摘要
根据勘察成果建立滑坡地质模型,通过采用极限平衡法计算滑坡的稳定安全系数,然后利用拉格朗日有限差分法FLAC对滑坡的应力场、形变场的分布特征进行模拟分析,然后使两种方法相结合,既能反映边坡的稳定和变形之间的关系,又可以使用安全系数来评价边坡的稳定性,具有很好的工程应用前景。
According to the results of the investigation ,the geological model of the landslide is established .The landslide stability factor of safety is calculated by using limit equilibrium method first;Then,the stress field and deformation field of the landslide are simulated by using the finite difference method FLAC .Combination of the two methods can not only consider the influence of the deformation of the slope on the stability ,but also evaluate the stability of the slope with sta-bility factor of safety which is well known in geotechnical engineering .The proposed method will have broad application to the slope stability analysis .
