Description

technical field [0001] The invention relates to the technical field of tunnel excavation, in particular to an abnormal geological detection and analysis device, method and system. Background technique [0002] With the continuous development of deep and long rock tunnel construction, full face rock tunnel boring machine (Full Face Rock Tunnel Boring Machine, TBM) has been used more and more. Numerous engineering practices have shown that due to the complexity of stratum conditions and the sensitivity of TBMs to changes in geological conditions, TBMs will inevitably be seriously affected by abnormal geology during the excavation process, which may easily cause major accidents such as machine jams or even machine crashes. In order to avoid geological disasters and safety accidents during TBM construction, the most effective solution is to use advanced geological detection technology to identify abnormal geological conditions in front of the working face in advance, and to form...

Problems solved by technology

However, the seismic advanced detection technology of tunnels while drilling uses the acoustic wave signal excited by cutting tools to break rocks with a wide frequency band and complex frequency, which makes it difficult to identify effective waves, resulting in low detection accuracy; active source seismic advanced detection technology does not use effective three-dimensional space observation method, resulting in poor spatial positioning of abnormal geology, resulting in low detection accuracy; horizontal seismic wave section detection technology uses the acoustic signal generated by the cutter head cutting rock as the excitation signal, because the acoustic wave form and observation method are simple, the acoustic wave inversion evaluation The method is complicated, resulting in low detection accuracy

It can be seen that the existing advanced geological detection technology generally has the technical problem of low detection accuracy
