摘要：
为研究开放空间大尺度可燃气云爆炸过程对周边环境的影响，在新疆哈密的管道断裂控制试验场开展天然气管道全尺寸爆破试验时，提出一种基于高空三维测点布置的多通道联动采集测试方法，基于该方法选择合适的测试仪器并在现场搭建测试系统，得到在试验条件下开放空间一定范围内的冲击波超压，数据获取率平均为84.8%。根据获得的试验数据绘制出天然气管道爆炸后冲击波超压峰值随距离的变化曲线，3次试验的曲线变化规律一致，证明该测试方法针对大尺度气云爆炸冲击波超压的高空、多测点、远距离测试是可行的。

Abstract: In order to study the influence of large scale open space gas cloud explosion on the surrounding environment, a multi-channel linkage acquisition test method based on high-altitude three-dimensional site arrangement was developed in the gas pipeline blasting test field of HAMI-XJ pipeline full-scale burst test site. The shock wave pressure in a certain range of open space under the experimental conditions is obtained, the data acquisition rate is 84.8% on average. According to the experimental data obtained, the curve of the shock wave change after gas pipeline explosion is drawn.The curves of the three experiments are consistent, and it is proved that the method is feasible to measure the overpressure of large-scale gas cloud explosion shock wave at high altitude, multi-point and long distance.
