To investigate the influences of fissure dip angle and filling material on the rock mechanical properties, uniaxial compression tests were conducted on fissured sandstone specimens containing fractures with varying dip angles and filling materials. Digital Image Correlation (DIC) and Acoustic Emission (AE) techniques were employed to monitor the deformation and fracture processes. DIC was used to capture surface strain distribution and crack propagation morphology, and AE was utilized to monitor the crack evolution processes. The distribution characteristics of the RA-AF parameters were analyzed. The results indicate that the filling material prolongs the elastic deformation stage of the fissured sandstone and enhances its brittleness. The effect on the compressive strength diminishes as the inclination angle of the fissures increasing. The elastic modulus of the unfilled specimens is positively correlated with the dip angle of the fissures, while the elastic modulus of the filled specimens is not affected by the dip angle of the fissures. After filling, the strain distribution of the specimens is more uniform, and the crack propagation path becomes concentrated. The unfilled sandstone specimens with a fissure dip angle of 0° to 15° exhibit wing-shaped tensile failure, while those with angles of 30° to 90° show wing-shaped shear failure. All filled specimens exhibit mixed tensile-shear failure. The AE analysis results show that the crack propagation in the unfilled specimens is consistent with the DIC results, while in the filled specimens, tensile cracks are the main type and shear cracks are secondary. The filling materials significantly alter the mechanical behaviors of fissured sandstone. The failure mode and crack evolution are jointly controlled by the filling state and the dip angle of the fissures. The research results provide a theoretical basis for the stability analysis of engineering involving filled-fissured rock masses.

为探究裂隙倾角与充填物对岩体力学特性的影响机制，采用数字图像相关（DIC）技术和声发射（AE）技术，对单轴荷载作用下含不同倾角及充填物的裂隙砂岩进行力学试验。通过DIC技术捕捉试件表面应变分布及裂纹扩展形态，利用AE技术监测裂纹演化过程，分析RA-AF参数分布特征。研究结果表明：充填物使裂隙砂岩弹性变形阶段延长、脆性增强，其对抗压强度的影响随裂隙倾角的增大而减弱；无充填试样的弹性模量与裂隙倾角呈正相关，而充填试样弹性模量不受裂隙倾角影响。充填后试样应变分布更均匀，裂纹扩展路径集中；无充填条件下，裂隙倾角为0°~15°的砂岩呈翼形张拉破坏，裂隙倾角为30°~90°的砂岩呈翼形剪切破坏；充填试样则均为拉－剪复合破坏。AE分析结果表明，无充填试样裂纹扩展与DIC结果一致，而充填试样以张拉裂纹为主、剪切裂纹为辅。充填物显著改变了裂隙砂岩力学行为，其破坏模式和裂纹演化受充填状态与裂隙倾角的协同控制。研究结果可为含充填型裂隙岩体工程稳定性分析提供理论依据。
