速度参数在地质雷达探测中的应用研究

Study of the application of velocity parameters in GPR surveying

首先对速度参数进行了介绍说明,详细讨论分析了现场采集求取速度参数的速度分析CMP方法和WARR方法,并给出了传播路径、时距曲线和计算公式,后续通过已有地质雷达剖面介绍了进行速度判别的方法,并给出了计算公式,最后通过多个实例详细分析了利用现场进行的速度分析方法和剖面中求取速度的方法,进一步验证了方法的可行和有效性,能够满足工程勘察需要。

Firstly,the velocity parameters is presented in detail.The CMP and WARR methods are discussed in detail for the velocity analysis from the field data.The corresponding propagation path,the time-distance curve and formulas are presented.And then the methods to distinguish velocity of ground penetrating radar profiles is introduced,and the corresponding calculation formula is decuced.Finally the velocity parameter with the detailed analyzing of multiple instances,for further validate the feasibility and effectiveness of the method is obtained.
