作为库区重点研究的滑坡之一,在地质测绘、钻探及物理勘探等大量勘察资料基础上,全面阐述了小汊头滑坡的地质背景、形成条件及变形模式,评价了滑坡整体及前缘次滑体在蓄水前后各种工况下的稳定性,初步分析了滑坡失稳产生涌浪的影响程度及堰塞体溃坝对施工围堰的危害性。 As one of the key landslides studied in the reservoir area, on the basis of a large amount of geological survey, drilling and physical prospecting data, the geological background, formation conditions and deformation modes of Xiaodou Tou landslide are comprehensively expounded. The stability of the sliding body under various working conditions before and after water storage is analyzed. The influence degree of the surge due to the landslide instability and the hazard of the dam body to the construction cofferdam are analyzed preliminarily.
