摘要(Abstract)：

介绍了城市复杂环境基坑石方爆破开挖工程,采用深孔控制爆破技术,在主爆区采取大孔径,在爆区四周实施预裂爆破,并严格控制单段药量的爆破方式,能够满足设计施工要求,有效缩短工期。通过优化爆破技术参数,加强安全防护技术措施,可将爆破有害效应控制在允许范围内。
The deep-hole controlled blasting of city foundation pit excavation in complex environment was introduced.Deep-hole controlled blasting technology and large aperture in the main blasting area were adopted,presplitting blasting around and single dosage were controlled.It could meet the requirement of design and construction,and effectively shorten the construction period.Harmful effect caused by blasting could be controlled within the scope of the permission by optimizing blasting parameters and strengthening the safety technical measures.
