摘　　要：库岸稳定对水库蓄水后的安全和长期运行有重要影响,将常见库岸类型划分为基岩库岸、土质库岸、岩土混合库岸,探讨图解法和卡丘金法计算水库塌岸的结果差异,利用图解法对某水库塌岸进行预测。结果显示,随着距坝距离的增加,塌岸宽度先增加后减少,拟合曲线大致呈抛物线型,同时塌岸宽度大于100 m的严重塌岸贡献塌岸总方量的89%。该文的数据分析方法及研究成果对类似工程勘察设计、施工具有一定的借鉴意义。The stability of the reservoir bank has an important influence on the safety and long-term operation of the reservoir after impoundment.The common reservoir bank types are divided into bedrock reservoir bank,soil reservoir bank and geotechnical mixed reservoir bank.The difference between the results of the graphic method and the Kaqiujin method for calculating reservoir bank collapse is discussed.The graphic method is used to predict the bank collapse of a reservoir.The results show that with the increase of the distance from the dam,the width of bank collapse increases at first and then decreases,and the fitting curve is roughly parabolic,and the serious bank collapse whose width is more than 100 m contributes 89%of the total amount of bank collapse.The data analysis method and research results of this paper can be used for reference to the survey,design and construction of similar projects.
