Blasting Technology Application near Buildings
【摘要】 为了使主坝正常运行,使爆破开挖时的爆破振动对均质土坝不产生裂缝等不良影响,而确定的爆破振速安全控制标准取6cm/s、最大单响药量为50.9kg,控制爆破规模不超过3.0、工作预裂线装药密度为q线=420g/m、孔距、孔深及爆破位置的选定。
【Abstract】 To ensure the main dam safety operation and avoid the influence of blasting vibration to homogenous soil dam crack,the parameters are determined as:the safety controlled standard for blasting vibration velocity is 6 cm/s,the maximum single powder charge is 50.9 kg,controlled blasting scale is less than 3.0,and the charge density in pre-splitting line is 420 g/m.The distance,depth and location of holes are determined.
