| 中文摘要: |
| 探地雷达以其高分辨率准确确定地下障碍物方面发挥了显作用，主要阐述了地质雷达定位探测的方法原理，通过实例讨论了雷达定位探测的分辨率及深度问题，论述了天线中心频率、测量点距及天线间距的选取技术，并成功的应用于确定桩位下方的孤石体、局部软弱夹层、管线位置，经开挖及打桩验证，雷达定位探测的准确率很高。 |
| 英文摘要: |
| Ground penetrating radar has a function to ascertain underground obstructions with high resolution. The paper dealt with the principle basis of location probing of geological radar, discussed the problems of resolving power and exploration depth, and expounded the techniques of choosing antenna frequency, survey point intervals and distance of two antennas. The radar has been successfully used to ascertain the isolated stone body, the sofa layer and the underneath pipeline. Tested and verified by excavation and drilling, the accuracy of ground penetrating radar to ascertain the underneath obstruction is very high. |
