Abstract With the rapid development and construction of China’s transportation system, more and more projects are being conducted near existing buried pipelines, which will inevitably influence the safety of the pipelines. Among the safety issues related to buried pipelines, blasting during the construction of an adjacent tunnel is one of the most adverse factors for existing pipelines. To ensure the safety and normal operation of the pipelines, a method for determining the peak vibration velocity control standard for buried pipelines under blast loading is established in this study. The acceleration time-history function that acts on the rock mass under the blasting seismic wave is derived as external excitation acting on the pipeline. By using the acceleration time-history function as input and combining it with a dynamic and static analysis of the pipeline, the critical vibration velocity of pipelines under the action of blast loading can be determined by the von Mises yield criterion of the buried pipeline material. Using the Dashanpi No. 1 tunnel project in Shenzhen, China as a background, the critical velocity control standard for buried pipelines under tunnel blast loading can be set at 190 mm/s without considering either the initial defects or the corrosion conditions during the operation.

相邻隧道爆炸荷载下埋地管道的振动速度控制标准

摘要 随着我国交通运输系统的快速发展和建设，越来越多的工程在既有埋地管道附近进行，势必影响管道的安全。在与埋地管道相关的安全问题中，相邻隧道施工期间的爆破是对现有管道最不利的因素之一。为保证管道的安全和正常运行，本研究建立了爆破荷载作用下埋地管道振动速度峰值控制标准的确定方法。推导出爆破地震波作用下作用于岩体的加速度时程函数为作用在管道上的外激励。以加速度时程函数为输入，结合管道的动静分析，可通过埋地管道材料的von Mises屈服准则确定爆炸载荷作用下管道的临界振动速度。以深圳大山皮一号隧道工程为背景，隧道爆破荷载作用下埋地管道临界速度控制标准可设定为190mm/s，不考虑初始缺陷或运行过程中的腐蚀情况。
