【摘要】 本文简单介绍了地震波层析成像技术(Computerized Tomography,简称CT)的基本原理,并对硐间地震层析成像技术的特点和应用条件做了说明。以某水电站左岸部分平硐勘测为实例,利用硐间地震波层析成像法反演确定了该部位山体的波速分布情况,根据波速分布划分其岩体质量,确定地质构造及软弱岩带的空间分布,为水工枢纽工程布设提供了物探成果的地质解释资料。结果表明该方法具有分辩率高、图像直观、易于解释的优点。更多还原

【Abstract】 This paper presents the principle theory of.Computerized Tomography(CT),and describes the characteristics & application conditions of seismic CT in adit.Using the seismic CT in adit to investigate a power station located in the left bank of the River,the rock quality,geological structure and the spatial distribution of soft rock band can be identified according to the inversed velocity distribution of this mountain area,then provides the geologically explanatory data of geophysical exploration for the design of the power station.Meanwhile,it also demonstrates higher resolution,more expressive image and can be easily understood.更多还原
