摘要 爆破参数的选择直接影响着爆破效果,是爆破工程设计的重要内容。通过对爆破场区所处位置、地层岩性等因素的考虑,结合实际制订了爆破技术方案,并介绍了各环节的注意措施。针对南水北调辉县段东河暗渠工程的爆破施工,通过对振动监测和爆后效果的分析评价,表明所选择的爆破参数是合理的。可为后续施工提供参考。 Blasting parameters directly affect the blast effect.It is an important content of blasting design.Through analyzing the blasting area location,rock condition and other factors,the blasting technical scheme was designed based on the actual situation,and the various measures were introduced.Blasting test has been carried out on the buried culverts engineering at the East River of Huixian County in the South-to-North Water Transfer Project.Analysis of the effects of vibration monitoring and post-blast showed the blasting parameters were reasonable.The successful experience could be referred by later works.
