【摘要】：某市供水隧道穿越海堤抛石堆积层及花岗岩,采用了顶管内气压条件下控制爆破的施工方案。介绍了该工程控制爆破的技术方案及有关爆破参数,并结合全程爆破有害效应监测的数据分析,总结了顶管内气压条件下控制爆破安全监测技术及监测结果。
[Abstract]:The construction scheme of controlled blasting under the condition of pressure in pipe jacking is adopted in a water supply tunnel in a certain city, which passes through the riprap accumulation layer and granite of seawall. The technical scheme and blasting parameters of controlled blasting in this project are introduced. Combined with the data analysis of monitoring harmful effect of whole blasting, the safety monitoring technology and monitoring results of controlled blasting under the condition of air pressure in pipe jacking are summarized.
