摘　　要：以紧水滩水电站混凝土拱坝两岸横缝监测开裂的实际情况为例,采用ANSYS有限元软件,考虑混凝土材料非线性和横缝接触非线性,分析了两岸坝肩横缝开裂对拱坝工作性态的影响,并对横缝开裂对坝体安全影响做出综合评价。The concrete arch dam of Jinshuitan Hydropower Project had seen transverse joint cracks at both abut- ments. With ANSYS finite element software, taking into consideration the concrete material nonlinearity and transverse joint contact nonlinearity, the author analyzed the influence of cracks on arch dam operating performance, and made comprehensive appraisal for dam body safety.
