Intrusion Detection Algorithm of Concrete Aggregate Placement Based on Grid Space
In order to improve the efficiency and volume rate of aggregate placement in concrete meso-model,an intrusion detection algorithm of aggregate placement based on grid space is proposed.In this algorithm,the aggregate information is stored in a grid space,and only the aggregate in the adjacent grid is taken out for intrusion detection during each placement,which greatly reduces the number of intrusion detection.Meanwhile,the aggregate intrusion detection is decomposed into the intrusion detection analysis of spatial line segments and triangular planes to achieve accurate solution.Examples show that the proposed algorithm can realize the modeling of concaved concrete aggregate with a volume rate of 65%.
