Abstract：According to the design principle of the pretensioned prestressing, the structural design of large-tonnage pre-tensioned prefabricated platform was carried out. The design and calculation method of the key parts in prestressing column and abutments were introduced. Especially, the structural design of the 1 500 t large- tonnage pressure abutments in Xinhui district of Guangdong was emphasized. The whole mechanical performance of the platform structure was analyzed by ANSYS software. The key parts of bracket in the abutment were tested in the field in order to compare and analyze its mechanical performance and the comparison analysis of its mechanical performance was also carried out. Finally, its safety and reliability were verified. The above research is of practical reference for promoting the construction technology of the large-tonnage pretensioned precast concrete platform.

Key words ： port engineering, large-tonnage, prestress, pretension method, precast, platform
