摘　　要：本文给了混凝土绝热温升新的表达式,既与试验资料符合得很好,又便于进行数学运算,由此得到新的水管冷却等效热传导方程。提出了混凝土坝施工期温度场的实用算法和简约算法,计算较方便,精度也较好。A new formula for the adiabatic temperature rise of concrete is proposed and the equivalent equation of heat conduction of concrete taking into account the influence of cooling pipe is derived. A practical metbod and a simple method for computing the temperature field in the construction period of concrete dams are proposed.
