摘　　要：通过运用概率评价中的Rosenblueth方法和定值法中的简布法相结合,对西藏江雄水库左坝肩山体蓄水前后的稳定性进行评价,得出失稳的可能性比较大,山体的加固处理是非常必要的结论。实践表明,该方法对西藏异常多变的高原气候下的边坡稳定性评价有重要的意义。Rosenblueth method in probability is combined with Janbu method in this paper to appraise the stability of the left bank mountain of Tibet Jiangxiong reservoir before and after impound, which shows that possibility of destabilization is large. So reinforcement of mountain body is very necessary. Practice indicates this method is important about the stability appraisement of slope under the unusually changeable plateau climate in Tibet.
