摘要
计算对接缝压实耗损、摩阻耗损和收缩徐变耗损,借助工程有限元ANSYS系统对块式、肋式转向块的功效适用性开展模拟计算分析,揭示预应力耗损和两种转向块结构型式对工程技术实现以及施工中的结构安全性影响,对同类桥梁建设提供技术参考。
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.
