【摘要】：基于功效系數(shù)法的基本原理,在綜合考慮滑坡的關(guān)鍵影響因素基礎(chǔ)上,選取滑坡規(guī)模、滑坡穩(wěn)定系數(shù)、當(dāng)日降雨量、潛在經(jīng)濟(jì)損失、受災(zāi)人數(shù)作為評價(jià)因子,建立了一種新的滑坡災(zāi)害風(fēng)險(xiǎn)評估方法,并將該方法應(yīng)用于瀑布溝水電站庫區(qū)12處滑坡災(zāi)害評估,評價(jià)結(jié)果表明,除麥地滑坡實(shí)際結(jié)果為Ⅲ級而預(yù)測結(jié)果為Ⅳ級外,結(jié)果準(zhǔn)確率達(dá)到91.7%。這表明基于功效系數(shù)法的滑坡災(zāi)害風(fēng)險(xiǎn)評估方法是可行的,為滑坡災(zāi)害的風(fēng)險(xiǎn)評估提供了一種新的方法。
[Abstract]:Based on the basic principle of efficacy coefficient method, the scale of landslide, landslide stability coefficient, rainfall, potential economic loss and the number of people affected by landslide are selected as evaluation factors on the basis of comprehensive consideration of the key influencing factors of landslide. A new method of landslide hazard risk assessment is established and applied to 12 landslide hazard assessment in Pubugou Hydropower Station reservoir area. The evaluation results show that the actual landslide results are grade 鈪，
