The Finite Element Analysis of Temperature Effect on Pump and Sluice During the Construction Period

摘要

The crack of concrete structure is commonly aroused by temperature action during construction period. The base slab of the water gate is the important structure, and in this paper, non-steady temperature field and temperature creep stress field are researched. Temperature creep stress field has the influence on the strained condition of the base slab, and a conclusion is draw: temperature stress has certain influence on the base slab of the water gate. The temperature stress of the base slab is improved to a certain extent, if the concrete has additive.
