摘要
该滑坡地处长江左岸万州区,体积360×104m3,目前滑体上存在局部拉裂,待三峡库区蓄水升高后,滑体前缘处于175 m水位以下,滑体稳定性进一步下降,对坡体上的居民以及三峡库区都将造成极大危害,影响严重。在深入分析滑坡地质特征、结构特征和变形特征的基础上,对滑坡的成因机制和影响因素进行了深入研究,并结合定量计算评价其稳定性,最后提出相应治理措施。
The landslide lies in Wanzhou district, left of Yangtze River, the volume of which is 360 ×10^4 m^3. At present the landslide body is partly pulled apart. If the conservation storage of reservoir area of Three Gorges rises, the anterior margin of landslide body is under 175 m water level, the stability of landslide body will drop further, and the residents on the body and reservoir area of Three Gorges will be endangered greatly. The influence is serious. On the basis of analysing in depth on the geological characteristic , structure characteristic and deformation feature of the landslide,the authors study the origin cause of formation mechanism and influence factor in depth, and appraise its stability combining quantitative calculation. Finally the corresponding controlling measures are brought forward.
