摘要
通过大型有限元分析软件ADINA,计算边坡在不同情况下的安全系数,将部分评价因子敏感性分别进行了分层比较分析,进而得出该因子对边坡稳定性的影响程度,赋予一定比值,提出一种权重确定方法,该方法相对客观地反映了在不同位置下部分因子对边坡安全的重要性以及同一位置下不同因子对边坡安全的影响大小。
Based on the finite element analysis software——ADINA,the safety factors of the slopes under various conditions are calculated;in which the sensitivities of a part of evaluating factors are comparatively analyzed in layers,furthermore,the impacting degrees of the factors are obtained and a method of weight determination is put forward herein by putting certain ratios on them.With this method,the importance of a part of the factors to the slope safety at different locations as well as the impacting degrees of different factors at the same locations can be objectively reflected
