| Abstract: | In this paper, compaction loss, friction loss and shrinkage and creep loss of the joint are calculated, and the application of finite element ANSYS system to block and rib steering block is used to analyze the effect of prestress loss and two types of steering block structure on engineering technology realization and structural safety in construction. It is valuable for technical reference in the construction of similar bridges. |
