| 摘 要： | 城市隧道周围居民区及构建筑物对爆破震动敏感，爆破减震成为关注的问题。在分析爆破爆轰波传播规律基础上，设计了复合装药结构以减少爆破震动。该复合装药结构由大小药柱组成，可使爆轰波径向传播，减少了保留岩体冲击波能量，从而达到减震效果。通过工程应用表明该装药结构爆破减震效果良好，同时具有较高的岩体破碎效率。 |

| Abstract: | The urban resident and buildings are sensitive to blast shake, so the blast shake weakening design was always a critical problem for urban city tunnel blast construction.According to the analysis of explosion wave diffusion properties, a compound charge structure was provided for blast shake weakening in this paper.This compound charge structure consisted of a big charge column and a small charge column, which led the explosion wave diffuse into the radial direction.The shock wave energy to the reserved roc... |
