Abstract
Taking the head bay of the Changzhou hydro⁃junction No.1 lock for instance, the study was carried out to analyze the temperature changes of lock head concrete by using the finite element software. With the consider⁃ation of interaction among hydration heat, air temperature, and layer thickness of structure, analog computation for concreting of lock head was initialized during construction period. Meanwhile, on the premise of results of tempera⁃ture field, the changes of concrete stress during construction period were analyzed by using Sequential Coupled⁃Field Method to initialize the Thermal⁃Structural Coupling Analysis on concreting of lock head construction. The re⁃sult of the reasonableness test manifests that ANSYS finite elements software can be applied to calculate the overall stability, stress and strain and other elements in the lock head with high accuracy and vividness, and better simulate the influence of construction conditions on the ship lock cracks.关键词
