| 摘 要： | 采用有限元三维仿真方法研究宝泉电站下水库大坝上游混凝土面板设置垂直纵缝对坝体应力分布的影响,对纵缝间距进行了温度应力的敏感性分析.结果表明,温度荷载是研究分缝方案的重要因素,当面板分缝距离大于10 m时缝距对上游混凝土面板最大应力值影响不显著.

| Abstract: | The effect of longitudinal upstream facing temperature joint on stress distribution in the dam of Baoquan downstream reservoir is studied by use of the 3D finite element method;sensitivity of longitudinal joint distance on temperature contraction stress is analyzed.Results show that temperature load is an important factor in joint plan.When longitudinal joint distance exceeds 10m,the effect of joint distance on maximum stress in concrete facing is very small. |
