Based on fuzzy sets theory and tunnelling data bank, a fuzzy analogy method for design of rock support system in tunnelling is presented in this paper.
Some parts of the fence are 17 feet high, with metal plates extending ten feet below ground to prevent tunnelling.
He is also experienced in soft ground tunnelling using tunnel Boring Machine and NATM methods carried out in difficult ground conditions and at close proximity to important structures.
Progress in tunnelling after 2000 : proceedings of the AITES-ITA 2001 World Tunnel Congress, Milan, Italy, 10-13 June 2001. v.1, session 1-4, History and archaeology, underground construction and the environment
The workers were tunnelling through solid rock.
Nano-detection system design of atomic force microscope based on scanning tunnelling microscopy
Construction of the undersea and river-crossing tunnels has accumulated plenty of experience for the development of shield tunnelling.
compressed air tunnelling method
The effect of resonant-tunnelling appears in the structure.
Surely you’ve replaced tunnelling through snowbanks with exciting projects that just so happen to not require snowpants or mittens?
superconductive single-electron tunnelling effect
Poor-geology consolidation grouting in double-shielded TBM full face tunnelling
The sensors rely on quantum tunnelling, in which electrons take journeys that would not be allowed by the laws of classical physics, as long as the distances involved are tiny.
Grave protrusion coal seam tunnelling hydraulic cutting protrusion-dispelling measures is a new technology in the world.
Structural deformation of overlying subway tunnels induced by tunnelling
The prisoners had escaped by tunnelling.
Analysis and calculation of superimposed load induced by double parallel shield tunnelling
The expressway tunnels construction in Henan province used new Austrian tunnelling method, which emphasized on site monitoring and measuring, and improving design and construction using the results.
The system is in the state of the superposition of the two macroscopic quantum states. Thecoherent tunnelling between them leads to the energy splitting.
