- Abstract:

To address the limitations of existing surrounding rock mass identification methods based on TBM vibration signals in terms of feature extraction effectiveness and engineering adaptability, a novel surrounding rock mass perception method was proposed integrating wavelet scattering network (WSN) and long short-term memory network (LSTM) using TBM cutterhead vibration data. Firstly, relying on the spiral ramp project of the Beishan Underground Laboratory, a vibration monitoring system was mounted on the TBM cutterhead to acquire vibration signals during the TBM tunneling process. Then, a rock mass sensing database based on cutterhead vibration was established through a series of data preprocessing procedures, including stable tunneling segment extraction, noise reduction, and signal segmentation, combined with the matching of geological information along the tunnel alignment. Secondly, the WSN was employed to perform multi-scale temporal feature extraction from the preprocessed vibration signals, so as to enhance the feature representation capability and noise robustness. On this basis, a WSN-LSTM surrounding rock mass perception model was constructed by leveraging the inherent superiority of the LSTM network in capturing the temporal dependencies. The research results demonstrated that the proposed WSN-LSTM model achieved an accuracy of 93.7% on the test set, which yielded a 5.6 percentage points accuracy improvement compared with the wavelet scattering network-based support vector machine (SVM) model, and outperformed shallow machine learning models (random forest and LightGBM) based on amplitude-domain statistical feature extraction. These findings validated the superiority of WSN in feature extraction from TBM cutterhead vibration signals, as well as the necessity of capturing the temporal dependencies of cutterhead vibration features.
