摘　　要：以贵州某水库大坝工程为研究对象,采用混凝土面板堆石坝形式,通过三维有限元法及材料力学法,对该工程的高趾墙进行动力响应分析。结果表明,高趾墙底部所受截面应力均高于上部所受应力,应力差异均在2MPa范围内,最大应力集中在高趾墙与坝体底部连接位置。混凝土面板堆石坝高趾墙能够确保水库工程整体质量,研究成果可为水利工程高趾墙的施工与维护提供技术参考。Taking a reservoir dam project in Guizhou as the research object,the concrete face rockfill dam is adopted for construction,and the dynamic response of the high toe wall of the project is analyzed by three-dimensional finite element method and material mechanics method.The test results show that the section stress at the bottom of the high toe wall is higher than that at the upper part,and the stress difference is within the range of 2MPa.The maximum stress is concentrated at the connection between the high toe wall and the dam bottom.The high toe wall of concrete face rockfill dam can ensure the overall quality of the reservoir project and provide technical reference for the construction and maintenance of the high toe wall of hydraulic engineering.
