中文摘要：
为全面了解东南沿海地区在役混凝土公路桥梁结构的耐久性现状，在浙江省内开展了混凝土公路桥梁结构的耐久性现状调查，并对典型桥梁进行了详细检测．通过分析调查和检测的结果，发现这些结构普遍存在耐久性老化的现象，并且随环境条件不同在老化程度与老化类型上表现出明显的地区差异．因此建立混凝土结构耐久性环境区划标准以进行结构耐久性设计十分必要．最后提出了东南沿海地区混凝土公路桥梁结构耐久性设计、施工与评估的若干具体初步建议．
英文摘要：
The investigation of concrete highway bridge structures in Zhejiang Province is carrried out for an overall knowledge of current durability situation in southeast coastal area. Several representative bridges are selected for detailed inspection. The investigation and inspection results indicate that durability degradation varies in degree and style with environmental conditions of different areas significantly. Consequently a durability environmental zonation standard is required for concrete structural design. Some preliminary suggestions on durability design, construction and evaluation of coastal highway bridge structures are also proposed based on the analysis.
