摘要

2007年6月15日位于水布垭水库巴东县清太平镇的大堰塘滑坡发生滑动，激起高达50 m的巨大涌浪，造成了沿岸的人员伤亡。为了解决大堰塘滑坡引起的涌浪问题，把滑坡引起的涌浪分为体积涌浪和冲击涌浪两部分。根据体积守恒原理及块体水下运动的位移公式求出了初始涌浪的计算公式。把滑坡涌浪衰减过程分为急剧衰减和缓慢衰减两个阶段来考虑，并认为急剧衰减阶段的涌浪的衰减符合指数衰减规律，缓慢衰减阶段符合明槽水流的沿程水头损失规律，对其涌浪的传播和爬坡进行了深入探讨，并与实际调查结果进行了对比分析，该成果对水库库岸滑坡的涌浪传播的研究具有一定的参考意义。

Abstract

The Dayantang landslide in Qingtaiping town of Badong county

Shuibuya reservoir

slipped on June 15

2007. The climbing height of surge reached 50 meters

which caused casualty along the channel. In order to solve surge triggered by the Dayantang landslide

the surge is summarized into two kinds of surges

volume-surge and impact-surge

on the basis of the mechanism of landslide surge

respectively. The volume conversation law and the displacement formula of mass below water lever are used to calculated the initial surge height. The decay process of landslide surge is divided into sharp-decay stage and slow-decay stage; and it is assumed that the sharp-decay stage is a kind of exponential decay

and the slow-decay stage is a kind of water head loss with propagation distance in open channel. The propagation height and climbing height of landslide surge along bank are deeply discussed; and the calculation result is compared with survey of climbing surge. The result has reference significance for the research on propagation of landslide surge in the reservoir.
