Abstract： Prestressing construction technology is of great practical significance in the construction of road bridges. It aims to explore the application and effect of prestressing construction technology in road bridge construction， and conducts an in-depth study on the key issues. Using a combination of field observation and laboratory testing， the advantages and problems of prestressing construction technology in road bridge construction are summarized by monitoring and analyzing the construction process of several road bridge projects. The results of the study show that prestressing construction technology can effectively improve the bearing capacity and service life of road bridges and reduce the whole life cycle cost. However， there are still some problems in the practical application， such as the design of prestressing anchorage system and the selection of construction methods， which need to be further optimized and improved. Therefore， suggestions for improving prestressing construction technology are presented for better application in the construction of road bridges. In conclusion， the practical study of prestressing construction technology in road bridge construction has important theoretical and practical significance， and plays an important role in promoting the quality and safety of road bridges.
