地质雷达在隧道超前地质预报中的应用

摘要

This oaoer first briefly exolains the mechanism of GPR( Ground Penetrating Radar),data collection and some steos of the data oro-cessing. Then it comoared the detection interoretation outcomes of the advanced orediction for the right lane of Bawaiyang No. 1 tunnel with the re-al tunnel excavation,the results demonstrate that GPR is caoable of orooerly detecting the adverse geological ohenomena during tunnel construction.%简要阐述了地质雷达工作的基本原理、现场数据的采集方式以及一些数据处理的步骤，结合八外洋1号隧道右线的超前地质预报实例，将其探测解译成果和现场开挖情况进行了对比分析，结果表明地质雷达对隧道施工过程中出现的不良地质现象探测效果十分显著。
