| 摘 要： | 由温度荷载在拱坝产生的应力可以达到总应力的1/3~1/2.目前,水管冷却是降低拱坝大体积混凝土温度及温度应力的重要方法.为了获得在坝厚方向呈梯度分布的最优封拱温度场,研究了等间距布置人工冷却水管单向通水冷却方法获得温度梯度的方法,给出了单根水管冷却机理的理论求解过程.

| Abstract: | Temperature load is a main kind of load of arch dam.The stress aroused by temperature could occupy from 33 percent to 55 percent of total stress of arch dam.So far cooling pipe has become one kind of best cooling method to reduce temperature load of arch dam.In order to obtain the optimized temperature gradient,one-direction cooling pipe with fixed distance is mainly studied and the analytical solution is given. |
