摘  要：
泥石流是金沙江下游主要山地灾害之一,它对重大水电工程施工和运行期间的工程安全可能构成一定程度的威胁和危害。通过评估该区泥石流对重大水电工程的影响,指出泥石流对水电工程的影响主要表现在对施工道路、水电工程附属设施及移民安置、库区泥沙、坝区工程设施等4个方面。以金沙江下游白鹤滩电站库区黑水河泥石流为例,具体分析了泥石流对水电工程的影响。结果表明,黑水河泥石流可能堵塞主河,其堵塞回水和溃决洪水对白鹤滩电站建设的施工道路、临时设施有一定危害。此外,泥石流会将大量的泥砂带入库区,从而减少电站的有效库容。

摘  要：
The lower reaches of Jinsha River are the area that has the most serious problem of mountain hazards.Debris flow is one of the main mountain hazards in the area and it may cause damages to the construction and running safety of large hydropower projects.The evaluation method for the influences of debris flow on large hydropower projects was established firstly and then four ways(construction road,ancillary facility and resettlement,sand in reservoir area and engineering facilities in the dam area) of the influences were elaborated.Heishui gully,lying in the reservoir area of Baihetan hydropower station,was taken as a typical area to evaluate the influences of debris flow on the hydropower project.Results indicate that debris flow of Heishui gully may block the main river and thus its blocked backwater and outburst flood can cause damages to construction roads and some temporary facilities.In addition,a large quantity of debris flow materials can flow into the reservoir and the storage capacity of Baihetan hydropower station decreases consequently.
