摘要
本文结合柳林铺大桥加固改造工程实践,介绍了该桥产生病害的原因,加固改造施工技术及施工注意事项。特别在国内首次为旧桥增设橡胶支座,改善桥梁受力条件以及在不影响正常通车情况下加固改造的施工技术,具有较高的经济效益和社会效益,为旧桥的加固改造提供了新的途径。
Combining with the strengthening and rehabilitation of Liulinput Bridge,the causes of the troubles of the Bridge is analyzed,and technical measures of rehabilitation explained. It is notable that rubber supports were firstly used in our country to improve the loading condition of the bridge, and that the rehabilitation work was carried out without interrupting the traffic. This suggests a new way in the strengthening and rehabilitation of old bridges.
