Abstract

The present disclosure provides a system and method for forecasting fault fracture zones of TBM tunnels based on rock mineral analysis, including a mechanical arm device and a data analysis module mounted on the TBM. The main body of the mechanical arm with angular freedom, the front end of the main body of the mechanical arm is axially equipped with a laser Raman spectrometer detector, and the circumference of the laser Raman spectrometer detector is distributed with laser ranging modules to detect the laser Raman spectrometer. The distance between the detector and the surrounding rock ensures that the detector is always in vertical contact with the surrounding rock; the front end of the main body of the mechanical arm is provided with a rock image acquisition device; the data analysis module is configured to receive the rock image acquisition device, laser ranging module Based on the detection results of laser Raman spectrometer and detector, based on the data of multiple measuring points, the surrounding rock image, mineral composition and content change law with the face mileage are obtained, and then the fault fracture zone in front of the tunnel face is predicted.

Description

technical field [0001] The disclosure belongs to the field of fault fracture zone prediction carried by a tunnel TBM, and in particular relates to a TBM tunnel fault fracture zone prediction system and method based on rock mineral analysis. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] When the TBM tunnel construction encounters the fault fracture zone, it is very likely to induce serious geological disasters such as jamming, water inrush and landslide under the construction disturbance. Therefore, during the construction of TBM tunnels, it is necessary to accurately predict the occurrence of fault fracture zones. [0004] According to the inventor's understanding, different types of fault fracture zones have different disaster-causing mechanisms and models. For example, the central zone of a compressive fault bears huge pressure, the ...
