摘要
利用数值仿真计算方法,对高拱坝坝体分缝分块方式、浇筑温度、仓面保护方式、混凝土间歇时间、一期冷却方式(包括不同进水温度、不同水管布置、不同通水时间)等进行了系统研究,对影响坝体混凝土内部最高温度与断面平均温度的各种参数进行了敏感性分析,其结论可为设计单位制定温控措施方案提供决策依据.
By using the finite element numerical simulating method,this paper studies systematically the type of joints,placing temperature,protection ways on the top of a concrete dam,the first stage artificial cooling method including different cooling water temperatures,cooling lasting days and cooling pipe arrangement.The sensitivity of parameters related to the highest and average temperature of the concrete dam has also been studied.The results will do design departments a favor in stipulating thermal control methods of concrete dams.
