| At present,With The global land degradation, poor environment, resource shortage,population explosion, Earth’s environment for human survival has been overwhelmed,now the world in addition to adopt corresponding political and economic measures, have begun to focus on underground engineering excavation and utilization.As the main body of underground engineering-tunnel engineering along with the rapid development now traffic has been the cause of rapid development.. Practice has proved that carries on advance the geological forecast to the tunnel face before tunnel excavation,and at the same time, the process of tunnel construction by NATM and through a variety of measurement techniques for excavation tunnel surrounding rock dynamic monitoring, Can effectively guide the correct construction of the tunnel, Avoid the large landslide, mutation of gushing water and mud and other disasters which occurred due to geological conditions mutations.The paper based on the GPR monitoring and measuring technique in the tunnel disaster early warning application research for the selected topic, a systematic exposition of the GPR monitoring and measuring technology of theoretical foundation, field data acquisition and data processing.Combined with application result of the radar detection and monitoring measurement in Donglin mountain tunnel, through field investigation, collect relevant geological data, at the same time unifies the indoor analysis,according to the field data and the comprehensive application of geological analysis, research of ground penetrating radar and the monitoring measurement in the tunnel disaster early warning application.Through a combination of ground penetrating radar and the monitoring measurement in Donglin mountain tunnel typical application achievement, obtained the radar waveform and the monitoring data in tunnel disaster characteristics reflect, tunnel disaster early warning and provides technical assurance. |
