| Abstract: | The work of stress test and theoretical analysis of a 16 m prestressed hollow slab beam during the enlargement process is presented in this paper. Some rules of stress change in critical sections and the reasons of longitudinal cracks are found out from the obtained results and some useful conclusions are given, which provide reference for construction and design of similar type of bridges. |
