| 摘 要： | 唐古栋滑坡和雨日堆积体位于四川省雅江县境内的雅砻江流域,正在规划设计的雅砻江楞古水电站中坝址下游1.5km处,对大坝的安全构成潜在危险。本文以局部构造为线索,从雨日堆积特征分析入手,建立其与唐古栋滑坡在成因演化过程中的内在联系,通过对雨日堆积体的深入解剖,了解了唐古栋滑坡的形成过程,建立了该段河谷岸坡总体地质演化过程以及阶段性特征:唐古栋滑坡、雨日堆积体作为同一局部构造中的不同个体,其形成演化过程中存在必然的联系,代表不同演化阶段特征性产物。

| Abstract: | Tanggudong landslide and Yuri accumulation body are situated at 1.5km downstream from the middle dam site of Lenggu hydropower station in the Yalong River Valley, Yajiang county, Sichuan Province. They can be a potential hazard to the safety of the planning dam. Based on local geological structure, this study establishes the inner link between Yuri accumulation characteristics and the formation process of the Tanggudong landslide. The formation process of Tanggudong landslide are found out through analysis of the Yuri accumulation body characteristics. The evolution process of the bank slope in this valley and its periodic characteristics are established. The result shows that as different individuals in the same local geological structure, Tanggudong landslide and Yuri accumulation body have some inevitable connection during the process of evolution, representing classic products of different evolutionary stages. |
