摘要
在对测缝计观测资料定性和定量分析的基础上 ,采用拱冠分载法和三维有限元法对上标混凝土拱坝的结构性态进行了计算分析 ,并对坝体裂缝成因及其影响进行了综合分析和评价 .结果表明 ,坝体温度变化引起的应力重分布是坝体裂缝产生和扩展的主要原因 .
The structure behavior of Shangbiao concrete arch dam is calculated and analyzed by using crown cantilever load distribution method and three dimensional finite element method, based on analyzing joint meter's observational data. The dam body crack cause and influence for dam is comprehensive analyzed and appraised.
