摘　　要：采用全过程仿真粘弹性空间有限单元法对接缝灌浆水管冷却问题进行了计算研究 ,对冷却水温、冷却延续天数进行了敏感性分析 ,提出了只进行一期水管冷却 ,并在适当“超冷”情况下进行大坝接缝灌浆的建议 ,不但简化了施工步序 ,也有利于大坝的整体性 ,计算研究结果可供混凝土坝施工设计参考应用 .By using emulative visco elasticity three dimension finite element method, the water pipe cooling for joint grouting of concrete dams has been studied in this paper. Based on the analysis of sensitivity of cooling water temperatures and cooling lasting days, the authors suggest that the joint grouting can be processed under suitable “supercooling” environment and only make the first stage water cooling. If this suggestion is adopted, not only the construction process will be simplified, but also it will be favorable to make the dam integrated. The results can be applied to the construction design of concrete dams.
