摘 要: | 综合宏观判断、勘探资料分析及工程地质结构分析,利用ESR年代测定对构成下咱日堆积体的主要岩土介质的形成年代进行了测定分析,并在此基础上运用第四纪地质学、地貌学、区域河谷演化史等理论,对下咱日堆积体的成因机制及该地段的河流演化特征进行了分析。分析结论:下咱日堆积体天然状况下处于整体稳定状态,在工程建设及工程运行中也处于整体稳定状态,不会影响梨园水电站的建设。

Abstract: | The paper performs the determination analysis of the age of the formation of the major rock and soil mediums that constitute the Xiazanri accumulation mass by synthesizing macro judgement, exploration data analysis and engineering geological structure analysis using the ESR dating method, based on which the paper makes an analysis of the formation mechanism of the Xiazanri accumulation mass and of the characteristics of the evolution history of the river in the section by applying the theories of Quaternary geology, geomorphology and the evolution history of regional river valley. The analysis concludes that the Xiazanri accumulation mass is stable as a whole under the natural condition and is also under monolithic stability during both construction and operation of the project, and it does not affect the construction of the Liyuan Hydropower Project. |
