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。
Combining seismic tomography with elastic-wave transmethod measurement, a new way of delineating the range of bedrock blasting damage has been established. At the same time, combined with the attenuation equation of blasting seismic waves, the critical vibration velocities of the fractured rock mass in the Three Gorges Project are analyzed.
