综述了国内外周边缝、底缝拱坝的研究，从一些常规高拱坝的裂缝形式论证了设缝的必要性．对缝的结构型式、形状和接缝模拟的数值方法进行了讨论比较．指出分析研究周边缝、底缝拱坝应首先解决缝单元的形式、本构关系及高效求解方法，研究中应考虑施工期的温度应力等．同时，需对设缝以后拱坝的工作机理和失效机理进行研究，在此基础上，对其安全度需给以合理评估．
The domestic and international research on perimeter seam and bottom seam arch dam is reviewed. The necessity of seam crevice is demonstrated from the crack patterns of some conventional high arch dams. The structural type, shape and numerical simulation of joints are discussed and compared. It is pointed out that the analysis of the surrounding joints and the bottom seam arch dam should first solve the form, constitutive relation and efficient solution method of the seam elements. The temperature stress during construction should be considered. At the same time, it is necessary to study the working mechanism and failure mechanism of the arch dam after the seam crevice, and on this basis, the safety assessment of the dam should be given.
