【摘要】 文章介绍了地震波反射法、高密度电法(三电极法)和超前钻孔法三种探测技术的原理及现场测试,并对广乐高速公路长基岭隧道应用这三种探测手段进行的综合超前地质预报结果进行了分析研究。结果表明,间接预报和直接预报综合技术有一定的实用性;另外,单一预报方法都有一定的局限性,而综合地质预报方法能够实现优缺点互补,大大提升预报的针对性和可靠性。更多还原

【Abstract】 This paper introduces the principles and site tests of the three kinds of forecasting technologies: seismic reflection,high-density resistivity method with three electrodes and advanced drilling.Integrated tunnel geological prediction was combined with these three technologies and carried out in the Changjiling Tunnel on the Guangzhou-Lechang Highway.The results indicate that the integrated geological prediction has the complementarity of merits and demerits regarding the indirect and direct prediction.更多还原
