滑坡涌浪灾害物理模型试验研究综述

Review on research about disaster of landslide-generated impulse waves based on physical model experiment approach

为有效预防和减少滑坡涌浪灾害,采用定性文献综述方法从涌浪的产生、传播与衰减、爬高3个阶段对国内外物理模型试验相关文献进行全面梳理分析。结果表明:涌浪产生阶段的研究主要集中在波形特征的识别和初始波高/波幅的公式表达上,传播阶段的研究主要聚焦在涌浪形态和波高在空间的衰减上,而爬高阶段则主要关注爬高的求解。在现状分析的基础上,从致灾因子、承灾体、防灾减灾角度提出关注泥岩质滑坡体、滑坡体淹没率等具体的未来研究建议。

To effectively prevent and reduce the disaster of landslide-generated impulse waves,the method of qualitative literature review was used to overall comb and analyze the relevant literature of physical model experiment at home and abroad from three stages of generation,propagation and attenuation,and runup of impulse waves.The results showed that the research on the generation stage of impulse waves mainly focused on the recognition of waveform characteristics and the formula expression of initial waves height/amplitude,and the research on the propagation stage mainly focused on the impulse waves morphology and the waves height attenuation in space,while the research on the runup stage mainly focused on the solution of runup.On the basis of status analysis,some specific future research suggestions such as focusing on mudstone landslide body and the submergence ratio of landslide body were provided from the perspectives of disaster-causing factors,disaster bearing body,and disaster prevention and mitigation.
