摘　　要：南一水库大坝为混凝土重力坝，最大坝高９６．８ｍ。结合工程具体情况，采用全方位全历时动态温度控制，即区分坝体不同部位的施工环境和工作条件，如约束条件、气温、水温、湿度及应力状态等，进行适度的温度控制，取消了坝体纵缝。运行实践证明，取消纵缝的设计是成功的。Nanyi reservoir dam is a concrete gravity dam with maximum height of 96. 8m. In the light of actual project situations, adynamic temperature control was employed in all directions and in the whole Period of concreting. That is, according to construction environment and conditions of each part of dam body such as restriction conditions, atmosphere temperature, water temperature, humidity, stress, etc. the temperature was properly controlled to omit vertical joint of dam they. It has been proved by practical operation that dam design without vertical joint is successful.
