摘要:
提出了体外预应力加固体系的设计理论与构造要求,结合实际加固工程进行静载试验,比较加固前后桥梁在试验荷载作用下实际工作状态,测定结构的强度、刚度及抗裂性能,从而确认其加固效果.总结出体外索加固桥的具体施工步骤以及关键技术,可应用于工程设计.
Abstract:
According to extraneous prestressed strengthening practical bridge project a quiescent load test was conducted and the working behavior of the bridge under test load was analyzed. The strength, stiffness and resistance to crack were tested, and the effect of extraneous prestressed strengthening technique on bridge was properly assessed. This paper provides design theory and construction demands and sums up corresponding construction method and technological keys, which can be applied in engineering design.
