圈定基岩爆破损伤范围的声层析成象技术
Seismic Tomography Technique for Determining Damage Range in Bed Rock Blasting
-
摘要: 将地震层析成象技术与弹性波跨孔测量法相结合,形成了一条圈定基岩爆破损伤范围的新途径。同时,结合爆破地震波衰减方程,分析了三峡工程节理裂隙岩体临界振动速度的范围。Abstract: A new method for determining the rock damage range is presented for the first time on the basis of combining seismic tomography technique and elastic wave method. In addtion, the critical vibration speed in the jointed rock mass in Three Gorges Project is studied with the help of the attenuation equation for blasting seismic wave.
