摘要

为了解决水库库岸滑坡引起的初始涌浪高度问题，从滑坡涌浪的形成机制着手，把滑坡引起的涌浪分为体积涌浪和冲击涌浪两部分，并根据体积守恒原理、明槽中扰动波的传播速度及块体水下运动的位移公式求出了两者的计算式，体积守恒原理用于解决滑坡的入水体积与涌浪高度的关系，水流连续性原理用于解决传播的波速与波高的关系，黏滞力公式用于解决块体水下运动的位移与速度的关系。文章以新滩滑坡为例对初始涌浪高度进行了计算，得出了滑坡入水过程中初始涌浪高度先增后减以及它与滑坡速度的变化不一致的规律。

Abstract

In order to solve the initial surge height problem triggered by landslide in reservoir

the surge is summarized into two kinds on basis of the mechanism of landslide surge

respectively

volume-surge and impact-surge

and their heights are calculated by the volume conversation law

the continuity law of flow and viscous force formula in flow field. The volume conversation law is used to obtain the relationship between landslide volume and surge height

the continuity theory of flow is used to get the relationship between surge speed and surge height

and the viscous force formula in flow field are applied to solve the relationship between displacement and speed of mass in water. Taking Xintan landslide as an example

we can draw the conclusion that the initial surge height increases first and then decreases

and this change is different with that of landslide speed .
