中文摘要 | 冰滑坡入湖所致冰碛湖溃决洪水与泥石流是西藏冰川区突发的严重山地灾害。推得非均匀沙起动流速经验公式,并以d95作为起动粒径,导出溃决的临界漫溢水头高度H0算式。再导出冰滑坡入湖所致湖面上升高度和溃口处涌浪高度H2公式。综合得漫溢溃决的临界水文条件为:H1>H0,必定溃决;H1 |
英文摘要 | Flood water and debris flow caused by glacial lake burst caused by glacial landslide falling into the lake is a serious mountain disaster in glacial area of Tibet. After the experiment formula calculating threshold flow velocity of non-uniform sand was gotten with d95 of the glacial till in the dyke can be threshold sizes calculation formula of critical height H0of overflow head was guided. Then calculation formulas of ascendant height H1 of lake water surface and surge height H2 on burst mouth caused by glacial landslide falling into moraine lake are guided. Therefore critical hydrologic condition of moraine lake burst with overflow type are the burst is inevitablle as H1>H0 ; the burst is possible as H1 |
