摘要:
为确保某市地铁车站基坑爆破的成功实施，以爆破危害和块度控制为重点内容，通过优化爆破设计，综合采取多种安全有效、经济环保的防护措施，成功将爆破施工过程中的安全危害（爆破振动、飞石、有害气体、外来电流等）和环境危害（爆破噪音、粉尘等）控制在许可范围内；同时，运用LS-DYNA模拟岩石破碎效果，成功控制了大块率。实际爆破效果符合预期，工程效益显著。
Abstract:
Blasting hazards and lumpiness control were studied essentially to ensure the successful blasting of the foundation pit at a city subway station. The optimized blasting design and the safe and effective protection deployment, which is economic and environment friendly, made it practically controlled within a permissible range in view of the safety and environment hazards during exploration operations such as blasting vibration, flying fragments, noxious fumes, extra-neous electricity, blasting noise, dust, and so on. The rock fragmentation effect was simulated by LS-DYNA to help the successful control of large lumpiness rate. The actual blasting outcome was in good agreement with the expectation, demonstrating a rather remarkable engineering benefit.
