The Design and Implementation of HSP Real-time Prediction Technology Suitable for TBM Construction
( Song Lu ),( Cangsong Li ),( Xu Wang ),( Jianfang Ding ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2
In order to realize the real-time geological prediction that suitable for TBM construction tunnel, this paper take HSP geological prediction technology which can directly use rock-breaking vibrations generated by TBM cutters as foundation, and optimized the hardware and software of HSP system by analyzing the TBM fuselage and tunneling characteristics, so as to make it miniaturized, automated and intellectualized. The system has been installed on TBM for intelligent control and real-time prediction. During the TBM tunneling process: firstly, seismic reflection signals are collected continuously or frequently by geophones located in tunnel contours; secondly, the reflection characteristic parameters of stratum ahead of the tunnel face are acquired in real time through automatic processing; next, the effective pick-up and identification of unfavorable geological reflection interfaces are completed by intelligent recognition technology, which finally realized the prediction of unfavorable geological conditions. Therefore, through the optimization design of HSP method that suitable for TBM tunnel construction, real-time detection of the location, scale and properties of the unfavorable geological body can be achieved. This proposed technology can plays a certain role in promoting the efficient construction of TBM, which is of great significance.
