地质雷达在米亚罗隧道超前地质预报中的应用

Application of Geological Radar in Advance Geological Forecast in Miyaluo Tunnel

地质雷达是浅层地质勘探的有效方法,应用于预报裂隙带、断层破碎带、富水区围岩、岩溶洞穴等不良地质灾害。本文结合米亚罗隧道施工进行超前地质预报,通过对雷达波穿越该隧道不良地质的反应特征的分析,对不良地质和掌子面前方岩体构造情况做出准确预报,为保障施工安全提供有效指导。

Geology radar, which is widely used in the geological prospecting investigation, is employed in shallow geological survey to fractured zone, detect faulted zone, rich water region and karst caves. Combined with advanced geological forecast work of Miyaluo tunnel the reflection characteristics of radar wave pass through unfavorable geological condition are analyzed. In tunnel construction, the method can correctly predict unfavorable geological bodies and rock body structure in front of working face. It can provides effective instruction for practice to ensure construction safety.
