本文论述了预应力是本工程结构施工的重点难点,预应力的作用在本工程主要为平衡部分衡载,控制裂缝及挠度,故无粘结预应力的施工质量会直接影响到整个结构的使用质量。同时结合工程实例进行了分析,仅供同行参考学习。
This paper discusses that prestressing is the key point of the construction of this project. The role of prestressing in this project is mainly to balance the load and control the crack and deflection. Therefore, the construction quality of unbonded prestress will directly affect the use of the whole structure quality. At the same time with the engineering examples were analyzed for peer reference learning only.
