通过分析单裂缝岩石标本中弹性波到时分布、波震相转换和波振幅衰减等规律，进一步用波场及频谱量刻划介质横向不均匀性。Ｐ波震相遇裂缝端部后出现“之”字形波峰，分叉成折射Ｐ波、绕射Ｐ波，它的特征也依赖于发射源和接收点相对于裂缝的位置，当波以大角度斜跨裂缝和发射点在约裂缝半长度范围时波到时和振幅差别更大。对其研究有助于认识弹性波场在含断层结构中的复杂图象特征、在野外勘探中提高地震资料解释、断裂构造识别能力和提高弹性波在非完整岩石实验中的声发射定位等能力。
By analyzing the distribution of elastic wave arrival time, wave phase transformation and wave amplitude attenuation in single fractured rock specimens, the lateral heterogeneity of the media is further characterized by the wave field and spectral quantity. After the P wave encounters the end of the fracture, it appears as a zig-zag peak, bifurcates into a refraction P wave, and a diffracted P wave. Its characteristics also depend on the position of the source and the receiver with respect to the crack, when the wave is inclined at a large angle. The difference in the arrival time and amplitude of the wave is greater across the crack and the emission point at about the half-length of the fracture. Its research helps to understand the complex image features of elastic wavefields in fault-containing structures, improve seismic data interpretation in field exploration, identify fracture structures, and improve the acoustic emission positioning of elastic waves in nonholonomic rock experiments. .
