后张预应力空心板在港口工程中的应用

Application of Post-tension Hollow Slab in Port Engineering

由于后张预应力空心板的体积较小、预制安装简单方便,有利于规模化生产、运输和安装,已广泛应用于我国公路桥梁工程的上部结构中。结合福建地区港口工程中以后张预应力空心板作为上部结构的实例,介绍后张预应力空心板的设计、预制和安装的要点,并针对施工期空心板加载试验数据进行分析,总结在港口工程中采用后张预应力空心板的经验,供类似工程参考。

Since post-tension hollow slab is smaller in size,convenient and simple to prefabricate and install,advantageous to produce,transport and install in large scale,it is widely applied in the superstructure of highway and bridge projects in China.By combining with the port project of Fujian area in which post-tensioned hollow slab is used as the superstructure,the key points to design,prefabricate and install post-tensioned hollow slab are introduced.In addition,hollow slab load test data in construction is analyzed,the experiences of applying post-tension hollow slab in port engineering are summarized,which will provide the reference for the similar projects.
