探地雷达在涌山煤矿大桥勘探中的应用

The Application of GPR in Survey of Yongshan Coalmine Bridge

探地雷达是利用高频电磁脉冲的反射对地下目的体及地质现象进行探测的一种高效浅层勘探方法。随着电子计算机技术的不断发展,该技术的应用领域不断扩大。从探地雷达的基本原理出发,论述了探地雷达在涌山煤大桥桥址探测上取得的良好效果,并提出了一些探地雷达技术应用应注意的问题。

Ground penetrating radar（GPR） is an effective shallow exploration method which uses the reflection of high frequency electromagnetism pulse wave to detect the object and geologic phenomena underground. With the development of electron and computer technique, the application domain of this method is keeping enlarge. Based on the working principle of GPR, this paper discussed the good effect of GPR to pier prospecting in Yongshan coal mines. Some matters that should be attentive are posed while using GPR.
