我国经济在不断的发展,为桥梁、隧道和公路事业的发展提供了契机,这些项目得到了很大的发展,而且竞争越来越激烈。相关的单位和企业为了更好的应对竞争形式,在进行设计的过程中需要考虑一些因素,其中的设计多采用连续箱梁现浇支架设计,这种设计有很多的优点,如功能较多,较强的承载力,高效率和拆卸方便等,因此在中国使用比较广泛,本文重点对连续箱梁现浇支架设计、预拱度设置和连续箱的拆除进行了阐述。
The continuous economic development in our country provides an opportunity for the development of the bridges, tunnels and highways. These projects have made great progress and the competition is getting fiercer and fiercer. Relevant units and enterprises in order to better cope with the competitive form, in the process of designing need to consider a number of factors, including the design of continuous box girder cast-in-place stent design, this design has many advantages, such as more features, Strong bearing capacity, high efficiency and easy disassembly, so it is widely used in China. This paper focuses on the design of cast-in-place supports of continuous box girder, the setting of pre-camber and the removal of continuous box.
