摘要(Abstract)：

针对山西坪上应急引水工程复杂环境下集水廊道开挖的具体情况,提出了"两侧先行预裂、再横向拉槽创造临空面、最后进行主体廊道爆破"的施工方法,有效地控制了爆破振动及飞石对临近公路、路边民房、上方通讯线路及水源的损害,为同类工程提供了有益的经验。
According to the collector gallery excavation conditions of Pingshang emergency diversion project,the construction method of both sides presplitting firstly,transversal grooving for free face and collector gallery blasting of main body was put forward.And this construction method effectively controlled the damage caused by blasting vibration and flying stone to the nearby road,roadside civilian buildings,upside communication lines and water resource.Other similar projects could benefit from it.
