Abstract Bimrocks feature stiff blocks randomly distributed in a soft matrix. Despite their wide distribution in nature, their significant effects on the failure of rock structures such as slopes, mines and tunnels have not been fully understood. Bimrocks behave differently as compared with other rock types since they contain mix of blocks of different strength, size and volume distribution and a matrix of different physical and mechanical characteristics. The purpose of this study is to investigate deformation behaviour and crack development trends of bimrocks containing blocks of different sizes (small

摘要 Bimrocks 的特点是刚性块随机分布在软矩阵中。尽管它们在自然界中分布广泛，但它们对边坡、矿山和隧道等岩石结构破坏的显着影响尚未完全了解。与其他岩石类型相比，Bimrock 的行为有所不同，因为它们包含不同强度、大小和体积分布的块体以及具有不同物理和机械特性的基体的混合物。本研究的目的是研究包含不同尺寸块（小块）的bimrock的变形行为和裂缝发展趋势。
