| 摘 要： | 金沙江中游某拟定水电站坝址区下游存在一非基质结构岸坡,覆盖层厚度巨大,以白云质角砾堆积层为主。对角砾堆积体物质结构特征及成因机制进行研究,确定了其滑坡成因的性质,并分析了早期河谷边坡岩体可能的变形破坏方式。对该边坡稳定性分析表明,该古滑坡堆积体边坡自身结构长期处于稳定状态,没有发生古滑体复活或变形迹象,其整体不存在失稳条件。

| Abstract: | There is a bank slope of non-matrix structure at the site of a projected hydroelectric dam in the middle reaches of the Jinsha River. The spread of the bank slope is extraordinary thick,which is mainly composed of dolomatic brecciated accumulation body.The research is made on the brecciated accumulation body's features of the structure and genetic mechanism.The characteristics of the slope deformation cause are ascertained and the possible mode of early deformation and failure of the slope is analyzed.It shows that the ancient accumulation body' slope is stable for a long time and there is no indication and condition of deformation and destabilization for the whole slope. |
