Tunneling can compromise the safety and serviceability of existing buried infrastructure because settlements, crack openings, dislocations, material strains. A continuum-based soil-structure interaction model, implementing an equivalent Timoshenko beam, is used to evaluate excavation-induced settlements longitudinal deformations tunnels pipelines. Both single twin tunneling scenarios are examin...

Schaefer and Ruxton recently reviewed the mechanisms involved in plant deception, with an emphasis on pollination [1]. They proposed that generalised food deception evolves if plants exploit the innate preferences of pollinators, and thus represents a form of exploitation of perceptual biases (EPB). They contrast this with floral mimicry, which is viewed as a distinct phenomenon that might orig...

Identification of soil condition at the working face a tunnel boring machine (TBM) is key factor for efficiency and safety TBM tunneling. The paper presents first application Horizontal-to-Vertical Spectral Ratio (HVSR) method on microtremors induced by during tunnelling. innovative based development an easy-to-use economical early-warning system, which aims to confirm, or otherwise, profile es...
