摘要
利用SIR-4000型地质雷达对即将开挖的岩体进行探测,紧密结合工程地质条件,对探测成果进行分析解译,运用工程地质分析原理对即将开挖的隧道段工程地质条件进行分析,超前判知了隧道掌子面前方25 m范围内围岩岩体情况,提前做好了针对不同围岩岩体的开挖与支护准备,避免了施工风险,加快了施工进度。
SIR-4000 geological radar is used to detect the rock mass that is about to be excavated.Closely combined with engineering geological conditions,this article analyzes and interprets the detection results.By applying the principles of engineering geological analysis to analyze the engineering geological conditions of the upcoming tunnel section,the surrounding rock mass within a range of 25 m in front of the tunnel face was predicted in advance.Therefore,it has prepared in advance for excavation and support of different surrounding rock masses,avoiding construction risks and accelerating construction progress.
