| Abstract: | The placement of the post-pouring concrete zone is one of the measures for control of the temperature cracking during the concrete construction of large sluice gate piers. Based on the actual construction, the structural size of the post-pouring zone is designed, and then the key points and methods for the construction are discussed as well; with which better construction effect is obtained. Furthermore, the relevant influences from the placement of the zone on both the construction temperature and internal stress are analyzed through measuring the construction temperature and calculating the stresses concerned. |
