摘要
采用有限元法对浙江省门溪水库拱坝坝体内部结构应力进行分析,并采用有限元等效应力法对坝体和坝基(坝肩)接触部位应力进行复核.分析结果表明,采用有限元等效应力法由于消除了坝体和坝基(坝肩)接触部位的应力集中现象,计算得到的坝体最大主拉和主压应力均在规范容许范围之内,可为大坝安全评价提供参考.
The finite element method is adopted to analyze the internal structure stress of arch dam of Menxi reservoir in Zhejiang Province, and the stress of contact area of arch dam and its foundation （abutment） is reviewed using the finite element equivalent stress method. The results show that finite dement equivalent stress method can eliminate stress concentration on contact area, and the maximum principal tensile and compressive stress calculated using it both meet the regulatory requirements, and the results can provide a reference for arch dam safety assessment.
