Numerical Assessment of Subsidence and Adjacent Building Movements Induced by TBM-EPB Tunneling

Twin tunnel excavation in coarse grained soils: Observations and numerical back-predictions under free field conditions and in presence of a surface structure

“…In contrast, the case of twin tunnels, nowadays very common in many metro-line projects around the world (e.g. Rampello et al, 2012;Amorosi et al, 2014;Comodromos et al, 2014), has not received the same attention from the academic community and is lacking of an extensive experimental database.…”

An optimum metamodel for safety control of operational subway tunnel during underpass shield tunneling

“…Numerical simulation methods such finite element method and finite difference element method have been widely used. Several sophisticated numerical models have been established to simulate the construction process and back‐analyze the tunneling‐induced ground settlement …”

“…Several sophisticated numerical models have been established to simulate the construction process and backanalyze the tunneling-induced ground settlement. [2][3][4][5] In the construction phase, field monitoring is a significant tool to study the interaction between the tunnels and the adjacent buildings. A series of researches use ground and subsurface settlement monitoring to study the deformation characteristics and feed forward to tunneling design and construction.…”

Building response to tunnelling- and excavation-induced ground movements: using transfer functions to review the limiting tensile strain method

“…Buildings can be situated in different positions with respect to tunnel line and they can modify ground settlements depending on their restraint capabilities (size, weight, foundation type, etc.) (Comodromos, Papadopoulou & Konstantinidis, 2014;Potts & Addenbrooke, 1997). In Figure 1 (a), different buildings that are sagging (i), in the vicinity of the inflection point (ii) and hogging (iii) are schematically illustrated (settlement modification is not shown in Figure 1(a)).…”
