摘要
石羊江桥是一座6跨、简支钢筋混凝土梁桥,双车道。在中震及大震下,抗震能力薄弱。在对该桥进行旧桥承载能力加固的同时进行了抗震加固。阐述了该桥的抗震性能评价、抗震加固方案制定、抗震加固设计及实施情况。
The Shiyang River Bridge in Yunnan is a simply supported reinforced concrete girder bridge with six spans and two traffic lanes. The seismic capacity of the original Bridge used to be weak in the medium and strong seismic events. At the same time the carrying capacity of the Bridge was strengthened, the overall Bridge was seismically strengthened as well. In this pa- per, the assessment of the seismic performance, formulation of the seismic strengthening schemes, seismic design and implementation of the strengthening of the Bridge are dealt with.
