摘要
通过对预应力混凝土连续刚构病害调研、现状评估和有限元模拟分析研究,得出体外预应力加固连续刚构的适用条件及合理时机,提出了研究连续刚构桥体外预应力加固适用性条件,并通过实际工程案例对所提结论进行了验证,可为此类桥梁的体外预应力加固设计、施工和运营管理提供技术支持。
By conducting research on the diseases of prestressed concrete continuous rigid frames,evaluating the current situation,and conducting finite element simulation analysis,the applicable conditions and reasonable timing for external prestressed reinforcement of continuous rigid frames were obtained.The applicability conditions for external prestressed reinforcement of continuous rigid frame bridges were proposed,and the conclusions were verified through actual engineering cases.This can provide technical support for the design,construction,and operation management of external prestressed reinforcement of such bridges.
