【摘要】：針對潘家錚涌浪級數(shù)公式項數(shù)確定問題,結合近壩庫區(qū)某滑坡體,假定前緣點、中間點及后緣點固定滑移失穩(wěn)模式,分別進行滑速與涌高敏感性分析。結果表明,不能僅通過涌浪公式分析確定級數(shù)項數(shù);不同固定點滑移模式下的滑速大小依次為中間點、前緣點、后緣點;在涌浪級數(shù)項數(shù)相同的前提下,滑速與涌高基本呈線性關系;前緣點固定模式隨滑坡體方量增大,涌高先增大后減小;而后緣點、中間點固定模式隨著滑坡體方量增大,涌高先呈減小趨勢,然后局部增大,隨后減小�；麦wⅡ區(qū)后緣點固定滑面產(chǎn)生涌浪對壩體影響小,前緣點、中間點固定滑面產(chǎn)生涌浪對壩體影響較大。
[Abstract]:In view of the problem of determining the term number of Pan Jiazheng surge series formula combined with a landslide body near dam reservoir area the sensitivity analysis of sliding velocity and surge is carried out respectively on the assumption of fixed slip instability mode of leading point middle point and rear edge point. The results show that the number of series terms can not be determined only by the analysis of surge formula, the slip speed of different fixed point slip modes is the middle point, the leading point and the rear edge point, and the number of terms of surge series is the same when the number of terms of surge series is the same. There is a linear relationship between sliding speed and surge height, the front point fixed mode increases first and then decreases with the increase of landslide volume, and the latter, the intermediate fixed mode decreases first and then increases locally with the increase of landslide volume. Then it decreases. The inrush produced by the fixed slip surface at the rear edge of area 鈪，
