摘要(Abstract):
修建石(石家庄)太(太原)铁路客运专线,在Z7标段内有一10多万方的路堑需爆破开挖。该路堑地处稠密居民区旁,爆破开挖时除要求有效地控制个别飞石外,更要有效地控制爆破振动,确保数千户民房的安全。本文重点介绍了有效地控制爆破振动效应所采取的几项技术措施,经实际应用证明行之有效,为今后类似工程提供了成功经验。
There were some about more than 0.1 million m3 of cutting needed to be excavated by blasting in construction of Shi-Tai (Shijiazhuang to Taiyuan) passenger special railway line on Z7 section. With the cutting located close to residence zone in Jingxing,Hebei province,the blasting was required to be paid much attention to the effective control of blasting vibration beside the effective contain of flying stones so as to ensure the safety of thousand houses. The present paper focused on the introduction of several technological methods of effective control of blasting vibration. The excavation saw a well work of this employed methods and offered successful experience for similar engineering in future.
