摘要
开展河道崩岸评估方法研究工作对崩岸灾害预防有着重大作用。基于现有河道崩岸研究成果,对崩岸类型、影响因素进行了梳理,并将现有崩岸评估方法归纳为基于经验的崩岸评估、基于力平衡分析的岸坡稳定计算评估、基于岸坡崩退的数值模拟评估和河岸稳定性综合判断评估等4种崩岸评估方法。本文分析了各崩岸评估方法的优点和不足,并对其中存在的系统性问题进行总结,如崩岸机理研究不够深入、崩岸主导因素的权重无法确定、计算过程存在大量简化等问题,并对未来崩岸评估研究工作的开展提出了相关建议。
Research on assessment methods of river bank collapse plays an important role in the prevention of bank collapse.Based on the existing research results of river bank collapse,this paper sorts out the types and influencing factors of bank collapse,and summarizes the existing bank collapse assessment methods into four types:bank collapse assessment based on experience,bank stability calculation based on force balance analysis,numerical simulation assessment based on bank collapse and comprehensive judgment assessment of bank stability.This paper analyzes the advantages and disadvantages of each bank collapse assessment method,and summarizes the systemic problems existing in it,such as the lack of in-depth research on the mechanism of bank collapse,the uncertainty of the weight of the leading factors of bank collapse,and the simplification of the calculation process.Finally,some suggestions are put forward for the future research work of bank collapse assessment.
