| 摘 要： | 结合龙滩碟压混凝土重力坝材料特性,采用浮动网格有限元法模拟施工过程计算了设纵缝和不设纵缝两种情况下施工期和最大温降时的坝体温度场和温度应力场,计算分析表明,只要合理控制浇筑温度,即使不设纵缝,坝体温度应力也能满足设计要求。

| Abstract: | In view of physical properties of rolled concrete,the temperature and thermal stress distribution occurred during construction and the time of reaching maximal drop in temperature are calculated separately by using floating mesh finite element method to simulate the construction in the case of with and without longitudinal joints.The results demonstrate that the thermal stress could meet the design criteria even without longitudinal joints so long as placement temperature is controlled reasonably. |
