... and torque. The integrated framework provides a set of data processing methods including data cleaning, partition of full tunnelling cycles, feature extracting and model establishment. These data mining methods were applied to analyse the in-situ data of a water conveyance project. The results showed...

... (RBM) in a limestone quarry. Rock strengths were estimated from the thrust force and cutting depth and from the torque and cutting depth during shaft excavation with the RBM; the two strengths show a similar trend from the bottom of the shaft to the surface. In addition, the depth at the low rock...

... Decomposition (PPD) was developed to extract arbitrary data patterns easily and quickly from a large digital data sequence. The primitives use nine patterns. PPD with the primitives is applied for the detection of crack locations from torque logging data obtained during drilling. In a rotational drilling...

... of TBM in the field with 79% confident level. Result of sensibility analysis on the effect of Thrust and Torque on the PR shows that the maximum PR in given ground condition occurred in the optimum limits of Thrust and Torque. Keyword: penetration rate, artificial neural networks, Tunnel Boring Machine 1...

... performance prediction are compressive strength and tensile strength of rock material, frequency and orientation of rock joints. Effective machine parameters are TBM diameter, cutter line spacing, cutter diameter and tip width, total thrust and torque. All of these parameters are interrelated to each other [3...
