摘　　要：通过试验观测,对蚀坑深度、沿钢筋纵向的长度和钢筋横向的宽度3个参数进行定义,建立了钢筋蚀坑的三维模型,并在此模型的基础上进行有限元模拟,得到了蚀坑参数对钢筋应力集中分布的影响.Through experimental observations, this paper formulated definitions on the three parameters such as the pit depth, its reinforcement longitudinal length and lateral width, so as to establish a three-dimensional model of the reinforced pit. On the basis of this model, the finite element simulation was executed, which resulted in the influences of pit parameters on the stress concentrated distribution of reinforcement.
