摘　　要：为了研究坡度对冲击波传播的影响,在试验场构建了不同坡度的斜坡地形,通过超压测试系统获取了斜坡地形的冲击波超压。对比发现,在坡头前,测点的超压峰值和超压峰值达到时间与平地时的冲击波参数基本相同,冲量增大;上坡时,超压峰值、冲量随着坡度的增大而增大,超压峰值到达时间随着坡度的增大而减小;下坡时,超压峰值、冲量随着坡度绝对值的增大而减小,超压峰值到达时间随着坡度绝对值的增大而增大。得到了不同坡度时冲击波超压峰值和超压峰值到达时间相应的工程计算公式。In order to study the influence of slope on the propagation of shock wave,slope topography with different slopes was constructed in the test site.The shock wave overpressure on the slope was obtained using the overpressure measuring system.It is found that,at the front of the slope,the peak overpressure and its reaching time on the slope are basically the same as the shock wave on the flat ground,and the impulse increases.In the uphill propagation,the peak overpressure and impulse increase with the increase of slope,while the arrival time of peak overpressure decreases with the increase of slope.In the downhill propagation,the peak overpressure and impulse decrease with the increase of absolute slope value,while the arrival time of peak overpressure increases with the increase of absolute slope value.The corresponding calculation formulas of peak overpressure and arrival time of peak overpressure at different slopes are obtained.
