Research of construction control of long span continuous prestressed rigid frame bridges

With the augment of bridge span,cantilever construction has already become the main construction method in long-span bridge construction.Meanwhile,to the bridges built by cantilever construction method,in order to ensure the structural joining accuracy,the alignment and the internal force of finished bridges,and the final meeting elevation to the design requirement after using a certain period,construction control has also became more and more important in design and construction.In order to establish an easy and feasible construction method,took Yezhihu Bridge as the example to study bridge construction control of long span continuous prestressed rigid frame bridges.
