【摘要】：针对潘家铮涌浪级数公式项数确定问题,结合近坝库区某滑坡体,假定前缘点、中间点及后缘点固定滑移失稳模式,分别进行滑速与涌高敏感性分析。结果表明,不能仅通过涌浪公式分析确定级数项数;不同固定点滑移模式下的滑速大小依次为中间点、前缘点、后缘点;在涌浪级数项数相同的前提下,滑速与涌高基本呈线性关系;前缘点固定模式随滑坡体方量增大,涌高先增大后减小;而后缘点、中间点固定模式随着滑坡体方量增大,涌高先呈减小趋势,然后局部增大,随后减小。滑坡体Ⅱ区后缘点固定滑面产生涌浪对坝体影响小,前缘点、中间点固定滑面产生涌浪对坝体影响较大。
[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，
