摘　　要：高速公路网中绝大多数桥梁均为混凝土桥梁,桥梁病害直接影响着桥梁结构的耐久性和寿命,对桥梁结构进行检测和状况评定是掌握桥梁健康状态和病害发展的必要手段。根据河北省某高速公路62座混凝土桥梁的定测检查结果,总结了影响混凝土桥梁结构耐久性的主要病害,并对其成因进行了分析。Most of bridges in highways are all concrete bridges. Bridge diseases directly affect the durability and lon- gevity of bridge structures. Testings and evaluations of bridge structures are the necessary means that master bridge health status and disease development. According to test results of 62 concrete bridges in Hebei province, this paper summarizes the main diseases that influence concrete bridge structure durability,and analyses its causes.
