Factors influencing performance of hard rock tunnel boring machines
Intact rock properties together with rock mass characteristics should be well investigated for selection of proper tunnel boring machine (TBM) for tunneling in various ground conditions. This is due to the significant impact of rock mass characteristics on machine performance. TBMs are site specific and designed for optimal performance in given ground conditions. When selected and put to work a...
متن کاملEstimation of penetration rate of tunnel boring machines using Monte-Carlo simulation method
One of the most important parameters used for determining the performance of tunnel boring machines (TBMs) is their penetration rate. The parameters affecting the penetration rate can be divided in two categories. The first category is the controllable parameters such as the TBM technical characteristics, and type and geometry of the tunnel, and the second one is the uncontrollable parameters s...
متن کاملA Machine Learning Approach to Predicting and Maximizing Penetration Rates in Earth Pressure Balance Tunnel Boring Machines
Modern tunneling projects will often rely on a Tunnel Boring Machines (TBMs) rather than traditional drill and blast (D&B) methods, because of TBMs’ increased tunneling efficiency[1]. TBMs have a circular drill at the front, which can range in diameter from 1 meter to 19.25 meters, depending on the desired use for the completed tunnel. Applications of tunnels dug by TBMs range from underground ...

متن کاملCalculation of tunnel behavior in viscoelastic rock mass
Wall displacements and ground pressure acting on the lining of a tunnel increase with time. These time-dependent deformations are both due to face advance effect and to the time-dependent behavior of the rock mass. Viscoelastic materials exhibit both viscous and elastic behaviors. Thorough this study, the effect of different linear viscoelastic models including Maxwell, Kelvin and Kelvin-Voigt...
