摘要
通过爆破振动速度的现场测试和分析,研究了3种爆破条件下的爆破振动速度传播规 律,分析了一种特殊地形对爆破振动速度传播的影响效果。基于上述工作,讨论了爆破减振 保护层的减振效果,给出了允许的梯段爆破药量,较好地解决了两个部位混凝土浇筑和爆破 开挖之间的矛盾。
By the field test and analysis of blasting vibration velocity, the propagation regularity of blasting vibration is studied for 3 kinds of blasting cases. The influence of a kind of special topography on the propagation of blasting vibration is discussed. Based on the above work, the evaluation of the reducing effect of the protective layer on blasting vibration is presented. The allowable amounts of charges per delay are given. As a result, the contradiction between pouring concrete and blasting excavating in 2 construction positions is settled with satisfaction.
