摘要
岸滩侧蚀崩塌现象广泛分布于世界各大江河之中,是一种危害较大的自然灾害。季冻区河流受水动力-冻胀/冻融耦合作用,岸滩崩塌机理复杂,影响因素众多,其崩塌机理研究对河岸防护和河流综合治理具有重要意义。从岸滩崩塌机理与力学模式、岸滩崩塌及河床冲淤交互作用数值模拟、典型季冻区河流(松花江及黑龙江)河道演变研究三个方面,对当前该领域国内外研究现状进行了综述和总结,对季冻区河流崩塌机理及其数值模拟领域存在的不足和研究趋势进行了分析,包括重点关注水动力-冻胀/冻融耦合作用下岸滩崩塌机理与力学模式,以及水-沙-岸-床耦合模拟方法的建立等方面,以期为季冻区河流岸滩崩塌及其数值模拟研究提供一定借鉴和参考。
The phenomenon of bank erosion and collapse is widely distributed in major rivers all over the world,and it is a kind of natural disaster with greater hazards.The mechanism of bank collapse of the river in seasonal freezing region under the effect of coupling of hydrodynamic-frost heave/freeze-thaw is complicated with more influencing factors,of which the study on the collapse mechanism has an important significance for river bank protection and comprehensive control of river.From the three aspects of the mechanism and mechanical model of bank collapse,the numerical simulation of interaction between bank collapse and riverbed erosion and deposition and the study on the river channel evolution of the typical rivers in seasonal freezing region(Songhuajiang River and Heilongjiang River),the study status quo at home and abroad within this field is reviewed and summarized,while the shortcomings and study trends in the field of mechanism and numerical simulation of the bank collapse of the river in seasonal freezing region are analyzed,including focusing on the mechanism and mechanical mode of bank collapse under the effect of coupling of hydrodynamic-frost heave/freeze-thaw,the method for coupling simulation of water-sediment-bank-riverbed,etc.,so as to provide a certain reference for the study on the bank collapse of the river in seasonal freezing region and its simulation.for the study of riverbank erosion in seasonally frozen rivers.
