摘要
调查和分析了澜沧江乌弄龙水电站坝址区左岸高程21935m^22225m范围内分布的结义堆积体的物质组成表明,该堆积体为崩坡积堆积物、泥石流堆积物和阶地残留的砂卵石共同组成的复合堆积体,且自上至下呈多元结构特征.阐述了该复合堆积体的成因.并认为堆积体下伏基岩台座的支撑和阻滑作用,使其具有较高的稳定性.
A large-scale accumulation body, named Jieyi compound accumulation body, is located in the left bank of Wunonglong Hydropower Station from elevation of 1,935 m to 2,225 m in Lancang River. Investigation and analysis results of the compound accumulation body show that it consists of collapse accumulation, debris flow accumulation and grait accumulation remaining in fluvial terrace with a multivariate structure from top to bottom. After expatiation of its genetic analysis, it can be seen that the compound accumulation body is stably supported by the rock foundation foundation below.
