摘　　要：混凝土面板堆石坝高趾墙是一个三向受力体系,采用材料力学法和三维有限元法两种方法对高趾墙进行竣工期和蓄水期的结构应力分析。结果表明,两种计算方法所得结果基本一致,材料力学法可以简单、快捷的计算出结构大主应力的大小和位置,但该方法具有局限性,对于重要工程仍需用有限元法进行校核。The high toe wall of CFRD is a three--dimensional force system. The material mechanics method and finite element method are used to analyze the structural stresses of high-toe wall during construction completion period and water storage period respectively. The comparison of results shows that： （a） the two calculation methods can basically gain same conclusions; （b） the material mechanics method can simply and quickly calculate the magnitude and location of principal stress, but has its limitations, and so the structural stress of high toe wall in major CFRD project still need to be checked by using finite element method.
