摘要? 2013年11月22日發(fā)生的黃島管道爆炸事故共造成62人死亡,，136人受傷,。調(diào)查顯示，在排水管道內(nèi)部存在多處混凝土柵欄障礙物,，油氣在排水管道內(nèi)聚集爆炸產(chǎn)生的超壓和物體碎片是造成傷害的主要原因,。為了定量探究障礙物對管道內(nèi)油氣燃爆破壞效應(yīng)的影響，本文搭建了長3 m,、內(nèi)徑100 mm的油氣管道燃爆測試裝置,，在管道后半段可根據(jù)需要安置各類障礙物。在常溫常壓下以丙烷與空氣的混合氣為燃爆介質(zhì),，采用弱點(diǎn)火方式進(jìn)行了燃爆試驗(yàn),，研究了在不同障礙物阻塞率、數(shù)量和間距條件下管道內(nèi)部的超壓分布和變化,。

Abstract：

　　On November 22th 2013, in Qingdao, the Huangdao, pipeline exploded. In this accident 62 people died and 136 people were injured. The survey shows that the drainage pipe explosion overpressure and object debris were the main reasons for the huge damage. There are many concrete fence obstacles in the pipelines that may increase the explosion overpressure. In order to study the effect of obstacles on pipeline explosion, a 3m-long, 100mm-diameter device was built for oil and gas pipelines explosion tests. The device consists of 2 short pipelines and all kinds of obstacles can be installed in the second one. In the experiments weak ignition was used to ignite the mixtures of propane and air. The distribution and variation of overpressure in the pipeline were investigated with obstacles at different blocking rates, quantities and spacing.

Key words： propane ; explosion ; overpressure ; obstacle
