摘要(Abstract)：

南水北调中线总干渠与陕京天然气管线交叉,交叉处石方明挖约180.5万m3,本文介绍了在管道两侧50⁵00m范围内进行爆破施工方案和爆破试验的成果。对爆破振动观测结果进行了分析,确定了合理的爆破参数,确保了爆破开挖进度和陕京天然气管线的绝对安全,为其他类似管线周边爆破,提供了参考经验。
The segment of South to North Water Diversion was intersected the Shanxi-Beijing gas pipeline,with about 1805 thousand cube meter of stone ready to excavated.The present paper discussed the blasting construction scheme and test results which were carried out in the range of 50 to 500m between the two sides of the pipeline and analyzed the observation results of blasting vibration test,which resulted in a reasonable determination of the blasting parameter.The blasting construction programme based on the tests ensured the excavation schedule and the absolute safety of Shanxi-Beijing gas pipeline,offered a reference for similar engineering.
