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 کاملSteel-lined Pressure Tunnels and Shafts in Anisotropic Rock
For the design of steel-lined pressure tunnels and shafts in anisotropic rock, it is common practice to assume for the computation that the system stands in isotropic medium with the lowest stiffness measured in situ. In this paper, stresses and displacements in the steel liner of a particular steel-lined pressure tunnel are numerically assessed taking into account the anisotropic behavior of t...
متن کاملSimulation Analysis of Rock Braking Mechanism of Tunnel Boring Machine
Original scientific paper Aiming at answering the questions of wear and failure of hob in the rock breaking process, the rock breaking process was simulated in different broken rock conditions by using finite element method. The relationship between normal force, lateral force, rolling force and time was obtained by rock breaking simulation analysis on the single edge disc cutter. The rock stre...
متن کاملPredator-Prey Interactions between Shell-Boring Beetle Larvae and Rock-Dwelling Land Snails
Drilus beetle larvae (Coleoptera: Elateridae) are specialized predators of land snails. Here, we describe various aspects of the predator-prey interactions between multiple Drilus species attacking multiple Albinaria (Gastropoda: Clausiliidae) species in Greece. We observe that Drilus species may be facultative or obligate Albinaria-specialists. We map geographically varying predation rates in ...
متن کاملBoring Banks and Taxes
How do taxes in the financial sector affect economic outcomes? We analyze a simple general equilibrium model with financial intermediation. We formalize a trade-off between tax policies that burden the owners of banks and tax policies that burden households. We also study the implications of the financial sector’s exemption from value added taxation (VAT). Main results are that an increased tax...
