喜馬拉雅中部阿潤河谷高山環(huán)境下的冰湖潰決洪水研究
發(fā)布時間：2023-04-02 18:33
冰川湖泊潰決洪水(GLOF)是一種被研究人員廣泛認(rèn)識的自然災(zāi)害,其爆發(fā)后的巨大破壞能力對自然生態(tài)環(huán)境和人造基礎(chǔ)設(shè)施安全等都構(gòu)成嚴(yán)重威脅。因此,進(jìn)行GLOF風(fēng)險評估是非常必要的,特別是在有水電站的流域內(nèi),如果不進(jìn)行GLOF風(fēng)險評估,可能會造成巨大的社會經(jīng)濟(jì)損失。此外,還需要綜合匯編水文、地質(zhì)、地貌和氣候數(shù)據(jù),以便對水電站等重要項(xiàng)目進(jìn)行可行性研究和設(shè)計研究。值得注意的是,文獻(xiàn)中已有很多方法可用于評估冰湖潰決洪水。這些方法通過方法構(gòu)造的類型、評價特征的數(shù)量和選擇、評價過程中所需的輸入數(shù)據(jù)和主觀性比率來區(qū)分,有些是適應(yīng)環(huán)境設(shè)計的,有些是設(shè)計來適應(yīng)的。評價程序?qū)斎霐?shù)據(jù)的要求和主觀性的要求通常被認(rèn)為是其重復(fù)使用的根本障礙。最近的一項(xiàng)研究考察了這些方法在高山環(huán)境中的適用性。結(jié)果表明,所采用的方法均不滿足所有規(guī)定的標(biāo)準(zhǔn),且需要耗費(fèi)大量的人力、時間和成本,因此,需要一種新的方法來適用于高山環(huán)境中水電項(xiàng)目安全性評估。此外,由于現(xiàn)有的GLOF風(fēng)險評估方法的主客觀局限性,我們提出了一種新的、易于應(yīng)用的基于歷史冰湖潰決洪水流量和影響規(guī)模的四步篩選方法,應(yīng)用范圍更廣,不需要根據(jù)主題區(qū)域進(jìn)行適應(yīng)變化,這也允許成本...
