Soft soils are widespread in many areas of the East-West highway Algeria, covering large areas. Construction projects such as embankments, airfields, roads, and railways experience several problems due to their low strength permeability. This study used a fully dynamic analysis evaluate response embankment. The numerical was carried out using FLAC 2D version 8.10 software. main objective effect...

The research on the dynamic response and influencing factors of shield tunnel lining under earthquake demonstrates significant engineering value in guiding design antiseismic tunnels. In this paper, a nonlinear finite element model soil-tunnel interaction is established based FLAC difference software, then Mohr–Coulomb elastoplastic plastic damage are used to simulate characteristics soil tunne...

In order to study the stability of tunnels under static-dynamic load, a new large-scale model test system was developed. The composed static loading unit, dynamic data acquisition unit and bench, which were specially designed overcome technical problems test, such as control, high-rate strain measurement easy operation. used 3600 × 2500 mm in size larger load disturbance area than tests. It can...

In this study, the seismic performance of a 20-storey steel structure with mat foundation located on layered soil is investigated under an array strong ground excitations, which includes 6 far-fault and near-fault earthquakes. Eight different modes for layering have been considered in numerical simulation. FLAC 2D nonlinear platform has used to model near-realistic behavior. To end, hundred lin...
