长期预应力损失测试方法研究

Research on test methods of long-term prestress loss

针对目前长期预应力损失的测量方法进行了研究综述,并结合实践经验,对每种测试方法的优缺点作出了评述,以便合理选用预应力损失测量方法,掌握预应力损失规律,进而控制桥梁的长期性能,改善结构的耐久性。

This paper made research synthesis according to the measurement methods of present long-term prestress loss,and combining with the practical experience,made comments to the advantage and disadvantage of each method,so that reasonably selected the prestress loss measurement methods,mastered the prestress loss laws,so controlled the long-term performance of the bridge,improved the durability of the structure.
