摘要
爆破地震效应是爆破的主要负面效应,目前多采用爆破质点振动速度来表述地震效应的影响程度大小;同时爆破振动频率特性对结构体的破坏程度也有很大的影响作用,并随工程结构特性而异.从爆破震动频率特性的角度,通过理论计算和分析对爆破振动波频率特性诱导结构体破坏作用进行了研究,结果认为结构体对于介质中传来的爆破振动波的选择放大效应.
The blasting vibration is the most negative effect of the blasting,and the particular vibration velocity of blasting is mostly used to reflect the degree of blasting vibration now.At the same time,the frequency of blasting vibration influences the damage degree of the structure,and varies with the structure characteristic.From the point of frequency characteristic of blasting vibration,the effect of structure damage induced by the blasting vibration was researched based on theoretical analysis.The results ahow that the structure has the selective amplification characteristic on the blast wave from the medium.
