Abstract The blasting vibration speed and dynamic strain distribution characteristics of the pipeline under no pressure and different working conditions (different doses and different blasting distances) were analyzed through a full-scale embedded high-density polyethylene (HDPE) pipeline field blasting test, combined with the characteristics of the strata in the pipeline pre-burial site in Wuhan. The reliability of the calculation model and the parameters was verified by comparing with the field test data, combined with LSDYNA dynamic finite element analysis method. The dynamic response characteristics of HDPE pipelines with different operating conditions (different filling water level heights) under blasting vibration loads were analyzed. A safety control standard for the HDPE corrugated pipe blasting vibration speed was proposed, combined with the hoop allowable stress control criteria for pipeline operating conditions. Results indicate that the circumferential strain reaches the largest value when the HDPE pipeline is affected by blasting vibration. The combined vibration and the equivalent stress of the pipeline decrease with the increase of the water level in the pipe, and the combined vibration speed and the equivalent stress of the front explosion side of the pipeline are greater than those of the back explosion side at the same section. The maximum combined vibration of an empty pipe was 18.56 cm/s, and the equivalent stress was 0.912 MPa. The vibration speed and the main frequency of the X-direction at the dangerous section of the pipeline decrease as the water level rises, and these of the Y and Z directions increase as the water level rises. The safety control speed of the pipeline operating state obtained through the preparation of Mises yield strength was 25.79 cm/s.

运营充水状态高密度聚乙烯管的爆破振动响应特性
结合武汉市管道预埋地层特点，通过全尺度预埋高密度聚乙烯（HDPE）管道现场爆破试验，分析不同工况条件下（不同药量、不同爆破心距）无压状态管道爆破振动速度及动应变分布特征；结合LSDYNA动力有限元分析方法，通过现场试验数据的对比验证计算模型及参数的可靠性；分析爆破振动荷载作用下不同运营状态（即不同充水水位高度）HDPE管道动力响应特性；结合管道运营状态环向容许应力控制准则，提出HDPE波纹管爆破振动速度安全控制标准. 研究结果表明：当HDPE管道受到爆破振动影响时，环向应变最大；管道合振速与等效应力随管内水位高度的增加而降低，且管道同一截面处迎爆侧的合振速和等效应力大于背爆侧，最大空管合振速为18.56 cm/s，最大等效应力为0.912 MPa；管道振速最大位置处X方向振动速度与主频随水位高度升高而降低，Y、Z方向振动速度与主频随水位高度的升高而增加；通过米塞斯屈服强度准备得到的管道运营状态安全控制速度为25.79 cm/s.
