摘要: 通过预制裂隙砂浆试件模拟工程实际裂隙岩体,以研究在不同裂隙情况下及有围压作用时裂隙岩体的动力学响应问题。在模具中安装预设裂隙塑料片模拟实际岩层的裂隙倾角及裂隙贯通率,在试验中围压简化为正常金属环固定。基于正交试验方法,利用分离式霍普金森压杆试验装置(split Hopkinson pressure bar, SHPB)研究了不同倾角(0°、30°、45°、60°、90°)、不同贯通率(100%、 75%、 50%、 25%、 0%)的砂浆试件在不同围压下的动力学响应。试验结果表明:当倾角小于45°时,试件稳定性随裂隙倾角增大而降低,当倾角大于45°时,稳定性随裂隙倾角增大而提高,倾角45°为稳定性临界点,稳定性与倾角并非线性关系;试件贯通率的增大明显降低动力学强度;施加围压后砂浆试件产生了伪塑性变形,能有效提高动力稳定性,对于高贯通率试件表现尤为明显。该结果为进行地下工程裂隙岩体的强度分析提供参考。

Abstract: In order to study the dynamic response of fractured rock under the conditions of different cracks and confining pressures, precast fractured mortar specimens were employed to simulate the actual fractured rock. In the mold precast plastic sheet were installed to simulate the actual rock fissure angle and the penetration rate, and the confining pressure was simplified to normal metal ring fixture. Based on the orthogonal experiments, the dynamic response on mortar specimens under different confining pressures in different angle of tilt(0°, 30°, 45°, 60°, 90°)and different penetration rates(100%, 75%, 50%, 25%, 0%)was studied by SHPB test device. The results showed that when the angle was less than 45°, the specimen stability increased with reduced angle of fracture, when the angle exceeded 45°, the stability increased with increased angle of fracture, 45° angle of tilt was the critical point of the stability; stability had non-linear relationship with the inclination; the increasing of the penetration rate significantly reduced dynamics strength of specimens; confining pressure made mortar specimens produce a pseudo-plastic deformation, which could effectively improve the dynamic stability especially for high penetration rate of the specimen. The results provided a reference for the analysis of the underground engineering of fractured rock mass.

Key words: penetration rate, fractured rock, combined dynamic and static loading, angle of tilt, confining pressure, mortar
