【Abstract】 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.更多还原
