Research on Transient Temperature of Concrete Surrounding Spiral Case and Temperature Effect on Gaps in a Hydropower Station

Abstract:

The transient temperature field and creep of concrete surrounding a spiral case are analyzed with a three-dimensional method, based on ABAQUS. The mechanism of hydration heat and cooling pipes on temperature is studied. The distribution of temperature with construction is given. The effect of temperature on gap between steel liner and concrete is researched. It is concluded that the influence of the measure parameters and temperature is indispensable.
