为研究裂隙对岩土体声波参数的影响,运用声波探测技术对裂隙发育程度不同的岩样进行试验,采用小波分析及频谱分析处理声波数据资料,获得声波探测的各种影响因素,建立声波与岩体介质的参数关系,并对岩样裂隙位置和数量做出定性分析。分析试验结果表明,岩样裂隙数量越多,岩样波速越小、质量越差、声幅参数越小,衰减系数越大。由此得出结论,可根据该特征推测裂隙岩体的裂隙位置和发育程度,进而对岩体工程质量进行评价,从而指导岩体质量检测与评价工作的开展。
In order to study the influence of fissure on acoustic parameters of rock and soil, the rock samples with different degrees of fissure development were tested by using acoustic wave detection technology. The acoustic data were processed by wavelet analysis and spectrum analysis to obtain various influencing factors of sound wave detection. Rock mass media parameters, and to make a qualitative analysis of rock fracture location and number. Analysis results show that the more fractured rock samples, the smaller the rock sample velocity, the poorer the quality, the smaller the acoustic amplitude parameters, the greater the attenuation coefficient. The conclusion is drawn that the location and development of fractures in fractured rock mass can be inferred according to the characteristics, and then the quality of rock mass can be evaluated to guide the detection and evaluation of rock mass quality.
