    Given the complex geological conditions of Yongxing Tunnel No. 1, which is located near a buried oil pipeline along the high-speed railway route from Guizhou to Nanning, blasting excavation presents significant difficulties and risks. Prioritizing the safe operation of the pipeline, efforts are made to minimize the vibration impacts from tunnel blasting on the existing oil pipeline. This research employs both numerical simulations and field tests to analyze the effects of three different delay times and three types of spacing charge materials on reducing pipeline vibrations. The numerical simulation findings indicate that the optimal delay time for vibration reduction during blasting is 30ms, resulting in a maximum combined vibration velocity of 0.52cm/s, which is 20% and 29% lower than the velocities at 28ms and 32ms, respectively. Among the three types of spacer materials tested, soil material proved to be the most effective, achieving a maximum combined velocity of 0.46cm/s, which is 30.30% and 22.03% lower than those of water and air spacers, respectively. The results from field tests align well with the numerical simulations. The findings of this study can serve as a valuable reference for identifying optimal vibration reduction techniques and ensuring safe and efficient construction under similar conditions.
