中文摘要：
系统总结了细观刚体弹簧元法的理论框架,即随机骨料的生成过程、细观刚体单元的划分原理、刚体弹簧元模型的确定方法、本构关系的建立过程等,并评述了各国细观刚体弹簧元法的最新研究进展及成果;在模拟混凝土劈裂试验时,考虑劈裂试验的加载特点,对劈裂试件刚体单元的划分方法进行了局部调整。结果表明：细观刚体弹簧元法能够应用于混凝土劈裂试验的数值模拟。
英文摘要：
Authors systematically summarized the theoretical frame of the mesoscopic rigid-body-spring method,which included the generation process of random aggregates,the meshing technique of elements,the construction of the mesoscopic rigid-body-spring model and the development of constitutive law of the springs.In addition,the latest research advances and results on the application of mesoscopic rigid-body-spring method at home and abroad were reviewed.At the end,regarding of the loading characteristics of splitting test,the adjustment of meshing method of element was adopted for the sample in order to represent the test condition.The results indicate that the mesoscopic rigid-body-spring method can be applied to the numerical simulation process of splitting test of concrete.
