摘要

摘要: 基于地质灾害涌浪计算公式和局部水头损失理论,建立了地质灾害涌浪公式计算体系。该算法充分考虑了不同滑坡崩塌造成的涌浪效应、不同区域涌浪衰减的差异性和自然河道的沿程水头损失与局部水头损失问题; 大量采用地形参数进行计算,客观性强。以龚家方崩滑体产生涌浪为例进行了计算,其计算结果与实际调查值相关性非常高。结果显示:龚家方崩滑体产生最大涌浪高度为33.45m,急剧衰减区内平均100m下降4m、平缓衰减区内平均100m下降0.11m和在峡谷区向宽谷区传播时有扩大衰减效应的规律。

Abstract: This paper presents an impulsive wave formula calculating system. It is based on geohazard impulsive wave formula and local head loss theory. . It takes into account on varied impulsive effect generated by varied landslides, decaying difference on varied region, frictional head loss and local head loss. It adopts many topography parameters. So its result is strongly objective. This paper takes impulsive wave generated by Gongjiafang for example and analyzes the impulsive wave. The results are close to the results of field investigation. The biggest impulsive wave height is 33.15 m. It is concluded that in the rapidly decaying area, the impulse wave has an average decrease of 4 m in wave amplitude within the distance of 100 m. While in the mildly decaying area, that figure is change to 0.11 m. Also it is found that there is an amplified decaying effect when the wave propagates from gorge to strath.
