在水电工程地质勘测中,硐间、孔间所测弹性波,多为路经各点的综合射线速度值,对解释地质现象不够广泛和深入。作者利用弹性波射线交会的相关性,提出了射线速度解析法、用射线交会点法解析各交会点的弹性波速度值,构制出解析速度剖面。并通过实例阐明解析系数的选取对断面地球物理参数和地质结构的显示明显程度及射线速度法的应用条件。
In hydropower engineering geological surveys, the measured elastic waves between the boreholes and boreholes are mostly synthetic ray velocity values at various points along the route, which are not extensive and in-depth for interpreting geological phenomena. Using the correlation of elastic wave ray intersections, the author proposes a ray velocity analysis method and uses the ray intersection point method to analyze the elastic wave velocity values at each intersection to construct an analytical velocity profile. The example shows the obvious degree of cross-section geophysical parameters and geological structure, and the application conditions of ray velocity method.
