随机游走法在混凝土球形骨料投放中的应用

Application of Random Walking in Concrete Sphere Aggregates Simulation

介绍了利用随机游走法进行球形骨料数值模拟投放的方法,并阐述了球形骨料数值模型的生成、投放、游走及有效性判定的条件.骨料模拟投放的算例表明:基于随机游走的球形骨料投放方法能在较少的计算量下获得较高的骨料填充率,骨料投放结果与实际吻合,适用于各种混凝土细观结构的模拟.

The paper presents a new numerical simulation method of sphere aggregates packing based on random walking algorithm.Spherical aggregates numerical simulation model building,packing,walking and validity checking are proposed.The simulated cases of the aggregate generation verify the efficiency of the proposed method.It also demonstrates that the virtual results are consistent with the actual ones.The method can be employed to simulate the concrete meso-structure.
