In spite of the fact that the effect of earthquake on earth dams has been widely studied during the past decades, the complicated behavior of such earth structures against different seismological characteristics is still unknown. Such ambiguities necessitate more accurate studies using more comprehensive computation tools to achieve new results describing the behavior of such structures subject...

Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

Numerical simulations of centrifuge experiments examining a sheet-pile wall with liquefiable backfill are conducted and results compared against the experimental responses to evaluate numerical tools’ ability accurately predict seismic performance this geosystem. The platform FLAC constitutive model PM4Sand used for simulations, focus is placed on displacements. influence relative density (D R ...

In order to study the stability control mechanism of deep soft rock roadway and active support technology anchor-grouting flexible bolt, this paper takes west wing transportation Yuandian No. 2 Coal Mine Huaibei Mining Co., Ltd., Huaibei, China as research background. By analyzing occurrence conditions failure characteristics surrounding structural mechanical properties combined with elastic–pl...

Soil-liquefaction-related hazards can damage structures or lead to an extensive loss of life and property. Therefore, the stability safety against soil liquefaction are essential for evaluation in earthquake design. In practice, simplified analysis procedure associated with numerical simulation is most used approach evaluating behavior effectiveness mitigation plans. First, occurrence evaluated...

Underground structures can be severely damaged during strong earthquakes. Potential damage to infrastructure due uplift increases in liquefied soils. Several models used simulate soil liquefaction. This study presents a new numerical method estimate the overall response of shallow-buried tunnels and interpret liquefaction mechanism saturated sand around structure under seismic action. The stems...
