随着我国社会经济的不断发展,越来越多的基础设施涌现出来,桥梁工程项目也在不断的增长。在桥梁工程的施工过程中,后张法预制箱梁的张拉控制是非常重要的,其直接影响这桥梁工程的质量和使用寿命,所以,施工人员在施工过场中要重点注意后张法预制箱梁的张拉控制。本文就对桥梁施工后张法预制箱梁的张拉控制进行了简单的分析。 With the continuous development of our country’s social economy, more and more infrastructures have emerged and the number of bridge construction projects has been continuously increasing. In the process of bridge construction, the tension control of post-tensioned prefabricated box girder is very important, which directly affects the quality and service life of this bridge project. Therefore, the construction personnel should pay attention to the post-tension precasting Box girder tension control. In this paper, the tension control of prefabricated box girder after bridge construction is simply analyzed.
