| 摘 要： | 在实际工程中,由于某些因素,可能会导致已安装的预应力筋锈蚀,甚至出现误装、漏装预应力筋的现象。为了解决这些问题,有时候需要在相应的位置开洞。以广东省某桥漏装预应力为例,运用有限元分析软件ANSYS建立实体三维模型,对开洞后的结构进行弹塑性分析,并给出合理的建议,对同类工程有一定的指导意义。

| Abstract: | In practical engineering, due to certain factors, it may lead to installed prestressed reinforcement corrosion, even appearing the phenomenon of misloading and mising prestressed reinforcement. In order to solve these problems, sometimes it need to open holes. In this paper, a reinforced concrete bridge is relied on ,which lies in guangdong province.By the finite element analysis software-ANSYS, the three-dimensional entity model is established. And its elastic-plastic analysis is undertaken afer openning on top plates.It provide some reasonable suggestions and certain guiding significance for project of similar operation. |
