| 摘 要： | 本文的研究通过黄河上游茨哈峡水电站岸坡的变形特征,阐明了一类顺层高陡斜坡由倾倒变形转化为蠕滑-拉裂的斜坡变形破坏方式、演变过程及发展趋势,并对该岸坡的稳定性进行了分析评价。结果表明,目前该斜坡变形的发展已初步形成潜在折断面,并正处于蠕滑-拉裂变形阶段。从地质历史过程分析,其处于从稳定变形到不稳定破坏的过渡阶段。

| Abstract: | The present research has described a sort of slope deformation pattern which transform from toppling to creep-sliding and fracturing and their developing process and development tendency by researching the slope deformation characteristic of the Cihaxia hydropower station located at the upstream of the Yellow river.In addition,the stability analysis of the slope has been carried out.The result shows that the slope is now in the stage of creep-sliding and fracturing,and the potential unified slip surface basically has been formed currently.According to the method of geological history analysis,the slope is on the way from stability to instability. |
