| Abstract: | This paper deals with problems of temperature stress of the spillway dam section in the Three Gorges Project with relation to pouring without longitudinal joint,varied blocks of dam,spillway outlet, spillway face. Based on the above analysis,the problems,which require attention in the construction design of spillway dam section, are advanced. These problems have representativity and are of referencing value for working of construction scheme and temperature control in other dam sections of Three Gorges dam and analogous projects. |

| Keywords: | temperature field sudden drop of atmospheric temperature temperature control pouring without longitudinal joint longitudinal joint outlet spillway face stress |
