| 摘 要： | 本文从爆破震动影响因素入手,介绍了点爆源爆破震动的特点,分析了微差间隔时间、测点距爆区距离、药量分布等爆破参数对爆破震动的影响,用实测爆破震动波形论证了多段微差爆破时,爆破震动强度由微差间隔时间、测点距爆区距离、各段药量分布等爆破参数联合作用决定。当这三种参数达到最佳匹配时,就能达到最佳降震效果。

| Abstract: | Blasting vibration in a complex environment is not only easy to cause civil disputes,but even cause safety production accidents.Therefore,it is particularly important to minimize the impact of blasting vibration on the protected object.Through the blasting case analysis,based on the identification of the impact of blasting construction on surrounding houses,statistics and analysis of the effects of different vibration speeds on non-structural damage to houses.The law between vibration velocity and non-structural damage is studied.The safety threshold of the vibration speed is initially determined.The results have important implications for scientific and objective monitoring and evaluation of housing damage. |
