| 中文摘要: |
| 青岛某地铁车站处于环境敏感区，为有效控制爆破震动,保证周边紧临建筑结构物、管线的安全，在露天爆破中应用单孔起爆水压减振爆破技术。介绍了爆破方案的制定与实施。实践表明效果良好，不仅能够降尘降噪、保护作业环境、提高炸药能量利用率，同时改善了爆破效果，使岩石破碎较为均匀、提高了施工效率。 |
| 英文摘要: |
| As a certain station of the Qingdao Metro is located in an environmentally-sensitive district, the single-hole-water-pressure-shock-deducing blasting technique is applied to the open blasting operation there to effectively control the shock caused by the blasting,and to ensure the safety of the surrounding building structures and pipelines.The drafting and implementation of the blasting scheme are introduced in the paper.Practice shows that the scheme produces good effect,not only reducing dust and noise,protecting the site environment,improving the energy efficiency of explosives,but also improving the blasting effect,breaking the rock more uniformly and greatly improving the construction efficiency. |
