Overview

This study examines the influence of mud build-up on TBM operations, suggesting optimal strategies to enhance cutterhead efficiency.

Key Points

  • The study identifies that mud build-up increases torque and thrust in TBM operations, reducing efficiency significantly.
  • A model incorporating both the aperture ratio and mud coating effects is developed, improving load predictions during excavation.
  • Field monitoring data validates the proposed prediction framework, confirming its reliability for TBM applications.
  • Maintaining a larger aperture ratio is recommended as an optimization strategy to mitigate mud build-up and enhance efficiency.
