在隧道开挖过程中,提前发现隧道前方的地质情况,为施工方提供准确的地质资料,对减少和预防工程事故的发生非常重要.通过采用地质雷达法对南罕隧道进行地质超前预报分析,结果表明:地质雷达法在超前预报隧道中不良地质因素是可行的,结果真实可靠,可为其它隧道施工超前地质预报提供参考与借鉴.%In the tunnel excavation process,it is very important to early find the geological conditions in front of the tunnel and to provide accurate geological data for the construction side for reducing and preventing the occurrence of engineering accidents.The Ground Penetrating Radar (GPR) is used for geological prediction of Nanhan tunnel,and the results show that the GPR is feasible in the advanced geological prediction of tunnel,the result is true and reliable,and it can provide reference for the advanced geological prediction of other tunnels.
