... and the radial stress at the elastoplastic junction after excavating the surrounding rock. A new rockburst criterion is proposed based on the mechanism for throwing-type rockbursts and catastrophe theory. Meanwhile, a new multi-factor index for identifying rockburst classification is given based on rockbursts...

...M. Ghadrdan; T. Shaghaghi; A. Tolooiyan Generation of negative excess pore-water pressure (NEPWP) due to the excavation of saturated soils under undrained conditions and the dissipation that follows over time may result in different short- and long-term slope instability. The NEPWP generated due...

...S. Yasar Partial-face rock excavation machines, which are equipped with conical picks form a major share in the mineral production and in the roadway excavation for underground mines. Consequently, the performance of these machines plays a key role for the success of the project where...

...G. Spagnoli; C. Bosco; P. Oreste The inclination of the cutting bits has a strong influence on the excavation energy in rocks. As matter of fact, a correct prediction of the cutting forces acting on the bits is very important to geotechnical engineering. Several cutting tests at 1 m/s cutting...

... and the equivalent excavated area method. It was found that this proposed solution was in better agreement with the field data. In addition, the extensional analyses of settlement, horizontal deformation, and contours and vectors of soil deformation around the DOT shield tunnel were also carried out. The DOT...

...X. S. Shi; I. Herle Clay mixtures are a by-product from open pit mining during the excavation of various soil layers. The mechanical behaviour of landfills composed of these clay mixtures is complex. In the present study, two clays were used to produce soil mixtures artificially in the laboratory...

The aim of the project is to implement a fast and accurate method for the simulation of underground excavations without the need for the generation and subsequent refinement of a mesh. The main differences to the above-mentioned publications on the isogeometric BEM...
