摘要
Abstract
Aiming at the temperature change occurred during the staged-placement of concrete for the construction of Tanghe Culvert Aqueduct on the main channel of the Mid-route of South-to-North Water Transfer Project, the simulation on the temperature field during the construction is made with a large finite element calculation software, and then the law of the temporal-spatial distribution of the temperature field throughout the construction of the aqueduct is obtained. Furthermore, the calculation result is compared with the data measured from the site and it demonstrates that the temperature during the concreting is more largely impacted by the relevant structural size, I. E. the larger the size is, the higher the internal temperature rise is to be along with the slower dissipation of the hydration heat inside of the structure. Generally, this study result has a referential significance for the a-nalysis of temperature stress and temperature control during construction made by the other similar projects.关键词
