摘要
当设计要求人工挖孔桩须穿过较厚的中风化岩层,嵌置于微风化岩层时,给施工造成了很大的困难,采用爆破技术能很好的解决这一施工难题,本文介绍爆破施工的技术参数设计及振动监测测试。
When a design requires manual excavation pile must to go through thick medium weathering rock layer,fixing it in light weathering rock layer,it creates great difficulty to construction.Blasting technology is a good way to solve the problem.The author introduces blasting construction technology parameters design and vibration monitoring.
