Abstract
The present invention provides a vibration and strain monitoring method for key positions of a tunnel boring machine (TBM), and belongs to the technical field of real-time monitoring for underground construction of the TBM. The present invention aims to provide a monitoring device and an all-weather monitoring and forecasting system thereof. The present invention acquires monitoring data through vibration and strain sensors and a wireless data transmission system, thereby realizing long-term real-time monitoring for vibration and strain states of key positions of a main machine system of the TBM during operation, reminding operators in time for maintenance and repair, preventing fatigue breakage on key weak positions of the main machine system of the TBM and ensuring safe and reliable operation of the TBM. The present invention further provides an evaluation method for strain states of positions which cannot be measured, i.e., an equivalent mapping method, thereby building a set of vibration monitoring and strain monitoring systems for the tunneling process of the key positions of the main machine system of the TBM.
