摘　　要：钢筋混凝土构件是港口码头结构中的主要组成部分,研究其构件在服役一段时间后混凝土强度的分布特征以及时变规律具有重要的实际意义。对大量混凝土强度的检测数据进行统计分析,采用W检验法对混凝土强度进行了概率分布类型的拟合检验,验证了采用正态分布的可行性,并给出了采用不同检测方法混凝土强度的参考值;通过统计不同年限混凝土强度的实测值,采用回归分析的方法得到回弹法测得的混凝土强度值与服役年限之间的关系。Reinforced concrete members are the main components in the structure of ports. Studying the component in service after a period of time has important practical significance to study the distribution features of the concrete strength and time-changing law in service after a period of time. Based on a large number of concrete strength testing data, we study the concrete strength for the type of probability distribution by W-test, which verifies the feasibility of using normal distribution, and gives the referential values of concrete strength by various test methods. Based on the real-measured data on the concrete strength of different number of years, we get the relationship between the concrete strength values of rebound
