Evaluation of jacking forces in weathered geology: geomaterial characterization and deep learning techniques
Category: Pipe jacking
Presenter: Dr. Chung Siung Choo
Organization: University of Technology, Sarawak Campus

Time: 10:00 US EDT, 15:00 GMT
Overview
The webinar focuses on the evaluation of frictional jacking forces for drives traversing fractured and weathered ‘soft rocks’. Some methods are presented for deriving equivalent rock strength parameters for the prediction of frictional jacking forces, including shear box testing on tunnelling rock spoil and in situ pressuremeter testing. However, existing frictional models are dependent on the strength parameters of the traversed geomaterials, with minimal focus on the significance of pipe jacking operation parameters. Case studies are presented, showing the application of deep learning techniques for visualising the influence of various operation parameters on jacking forces.
