摘　　要：为研究交叉裂隙对类岩石试样的物理力学性质的影响,制备了与岩石物理力学性质相似的类岩石材料,并对含不同角度主次裂隙的标准立方体试样进行单轴压缩试验,得到试样最终破坏模式及应力-应变曲线,同时利用RFPA对其进行了数值模拟研究,得出研究结果,可为认识水工裂隙岩石破裂规律提供参考。In order to study the effect of cross cracks on the physical and mechanical properties of rock-like samples,rock-like materials similar to rock physical and mechanical properties were prepared.Uniaxial compression tests were carried out on standard cube specimens with different angles of primary and secondary cracks,and the final failure mode and stress-strain curve of the samples were obtained.At the same time,the numerical simulation of the samples was carried out by RFPA,and the research results were obtained.It can be used as a reference for understanding the fracture law of hydraulic fissures.
