摘要
钻孔雷达技术是一种井中地球物理方法,它向地层发射高频电磁波,利用电磁波在地层中的传播特性来获取地层信息,从而解释地下构造,它具有较高的分辨率和较大的探测范围。钻孔地质雷达主要有两种工作模式,一种是单孔反射模式,另一种是跨孔层析成像模式,其他模式本文只是做了简要的介绍,两种模式的资料解释方法不同。本文详细讨论了钻孔雷达的应用进展以及国内外技术的现状,钻孔雷达由最初的核废料处理到现在广泛用于工程领域,说明其有很好的应用前景。
Borehole radar technology is a good geophysical method for borehole survey. It sends high frequency electromagnetic wave to the stratum, and we can get the stratum information from using the transmit characteristics about the electromagnetic wave. Therefore, we can explain the structure of stratum. Borehole radar has high resolution and large detection scale. It has two working modes： one is single-hole reflection mode, another is cross- hole tomography mode. The other modes are just simply discussed. It is different in the methods of data interpretation between the two modes. The progress of application and present technology both in our country and other countries are discussed particularly. Borehole radar primely is used to dispose of nuclear waste, and now it is utilized in most engineering areas. It shows that borehole radar has very good prospects in application.
