Research on Dynamic Response of Anchored Jointed Rock Slope under Traffic Load
Based on the actual slope engineering, the dynamic response characteristics of the anchored joint slope in acceleration, velocity, and anchorage cable axial force under traffic load are numerically simulated. The results show that the cable axial force of the anchored slope starts to rise from the anchor head under traffic load, reaches a stable value in the free section, and falls to close to zero in the anchorage section. The axial force of the anchorage cable decreases when the slope height increases. Within the free section of the anchorage cable, there is a "small platform", where the axial force value decreases slightly and rises again, and its position corresponds to the range in which the anchorage cable passes through the joint. The dynamic response of traffic loads to the monitoring points of the slope is related to the magnitude of the load, the frequency, and the duration of the vibration. It is also related to the distance from the location of the traffic load, the physical and mechanical parameters of the location, the existence of joints, cracks and other structural planes, and whether or not to take support measures. When the frequency of the traffic load is close to the natural frequency of the slope, the resonance phenomenon is easy to occur, and the damage of the rock and soil of the slope is increased.
