摘要
通过对铜陵桥塔柱历年检测数据的研究,从混凝土刚度的初始状态衰减过程、极限状态进行系统分析,研究了混凝土刚度在疲劳循环过程中的衰减规律及损伤情况,并提出了通过较少的检测数据来预测混凝土疲劳寿命的方法,从而为混凝土结构的寿命预测提供试验和理论依据。
Through research of testing data of tower column in Tongling bridge over the years, this paper carries out systematical analysis of initial condition, decay process and ultimate state of concrete rigidity, studies its decay regularity and damage condition in the process of fatigue cycle, and proposes the method to predict fatigue life of concrete through few testing data, in order to offer testing and theoretical basis for life prediction of concrete structure.
