【摘要】 在已知岩溶分布的地质剖面上进行超声波、地震波、电磁波层析成像试验,对弹性波速、电磁吸收分别成像。通过对不同的层析技术、方法及成像效果进行对比分析,得出了在桥梁基础岩体中,进行岩溶勘察超声波层析成像效果最佳的结论,对同类工程实践具有指导作用。更多还原

【Abstract】 In this paper, a tomography test, including ultrasonic, seismic and electromagnetic tomography, is presented for a geological section of known caverns. The test results are the images of both elastic wave velocity and electromagnetic absorption. The contrast and analysis of the diverse tomographic technologies, methods and imaging effects suggest that the ultrasonic tomography in the bridge’s bedrock is more effective in cavern survey than others, which is of significance to instruct congeneric engineering practices.更多还原
