摘要
调研了浙江省在役中小跨径混凝土桥梁现状。从桥梁跨度、修建年度、上部结构、荷载等级、技术状况、主要病害位置等几个方面对浙江省的中小跨径混凝土桥梁进行了归类统计分析;着重介绍了数量最多的现浇板梁桥和预制空心板梁桥中存在的一些典型病害。研究成果可为中小跨径混凝土桥梁在结构实时监测和管养措施制定等方面的研究提供基础性技术资料。
The medium and small span concrete bridges in Zhejiang Province were comprehensively investigated.Classification and statistical analysis with respect to the medium and small span concrete bridges in Zhejiang Province was carried out based on the bridge span,the construction period,superstructure,load,technical position and location of main diseases.Thus,the typical diseases of cast-in-place and prefabricate plate girder bridges,which were very plentiful,were introduced in detail.The research results can be used as basic technical data for the research of structural real-time monitoring,maintenance and management with respect to the medium and small span concrete bridges.
