摘要(Abstract)：

介绍了复杂环境下连续墙的爆破拆除技术。为了保证连续墙内侧已建地铁站台的稳定和防水的要求,采用了多循环少进尺与多打孔少装药相结合的爆破方法来控制最大段的装药量,从而保证了爆破拆除的振动和噪音控制在相应的国标范围内。
The paper discussed a blasting technology for the demolition of a continuous wall under complicated environment.For the consideration of the stability of the subway platform built inside the continuous wall and waterproof requirement,the method of the multi-cycle with less advancement accompanied by the multi-drilling with less explosive load was employed to control the explosive charge in the largest blasting capacity.The blasting demolition technology ensured the blasting vibration and noise to be controlled falling into the corresponding GB range.
