Due to a lack of awareness of environmental protection at the beginning of tunnel
excavation and the unique ecological vulnerability of karst areas, tunnel excavation is …

Small and medium-sized enterprises form a significant part of the economy of each country
with the greatest potential for growth and the impact on stabilizing the economy. Their …

This paper examines the role of TBM tail-grouting on surface settlement of coarse-grained
soils in urban area. The influence of tail grouting on the ground surface settlement is firstly …

Metro shield construction will inevitably cause changes in the stress and strain state of the
surrounding soil, resulting in stratum deformation and surface settlement (SS), which will …

In urban areas, engineers often need to assess tunnelling-induced displacements of piled
structures and the resulting potential for damage. This paper presents an elastic study of …

The influence of metro shield construction in congested urban areas on nearby buildings is
of great concern in practice. In this study, 3D-FEM model, validated through comparison with …

Tunnelling induced surface settlements can cause damage in buildings located in the
vicinity of the tunnel. Currently, surface settlements and associated building damage risks …

A discrete element method simulation was used to evaluate tunneling-induced ground
movement and the parameters of tunnel boring machines. The process of excavation by an …

A large scale model test and numerical simulation using three dimensional discrete element
method (3D DEM) were carried out in parallel to study the soil disturbance induced by earth …

During the initial design phases of complex multi-disciplinary systems such as urban
tunnelling, the appraisal of different design alternatives can ensure optimal designs in terms …
