The cutting of saturated rock is of importance to the deep sea mining, dredging and drilling industries. The presence of a fluid in the pores and surrounding the rock can significantly alter the cutting process compared to dry rock cutting through hy

When cutting rock hyperbaric, two cases may occur. The rock may encounter dilation or compaction due to shear. Dilation results in pore under pressures, while compaction results in pore overpressures. Dilation will increase the cutting forces conside

Abstract Pipelines in Arctic regions are at risk of being damaged by gouging ice masses(gouge depths of 5m-8.5m). As protection, pipelines can be buried in trenches. When trenching is performed in Arctic soil, subsea permafrost may be encountered. Su

This paper presents the results of a study into the application of neuro-fuzzy methods to model the performance of tunnel boring machines. A database consisting of over 640 TBM projects in rock has been used. It is shown that neuro-fuzzy methods give

To study the performance of rock cutting trenchers, data on the excavation and tool consumption rate of one type of trencher, the Vermeer T-850, were gathered on 16 sites. The data assembled were compared with the rock characteristics by studying the

A data driven approach to the modeling of unconfined compressive strength of rock samples is presented. Fuzzy logic approach is used to represent a nonlinear relationship as a smooth concatenation of local linear submodels. The partitioning of the in

This paper presents the application of a neural network for the prediction of the UCS from hardness tests on rock samples. To investigate the suitability of this approach, the results of the network are compared to predictions obtained by conventiona

A knowledge-based fuzzy model for performance prediction of a rock-cutting trencher has been developed. A trencher is a machine that uses a rotating cutting chain equipped with bits to excavate trenches in rock and soil. The performance of a trencher
