Relying on a deep foundation pit project in Beijing, using FLAC3D three-dimensional finite-difference software simulation combined with displacement monitoring data verification method, the excavation and three-pile two-anchor rod support system anhydrous sand pebble stratum are systematically analyzed, summed up variation law of formation stress, internal force soil nail, axial bolt, stress pi...

A series of shaking table model tests were performed to examine the effects deep cement mixing (DCM) columns with different reinforcement depths on seismic behavior a pile group in liquefiable sand. Due DCM column reinforcement, fundamental natural frequency ground increases noticeably. The excess pore pressure soils reduces increase columns. Before liquefaction, acceleration response improved ...

Seismically active areas are vulnerable to liquefaction, and the influence of liquefaction on pile foundations is very severe. Study pile-supported buildings in liquefiable soils requires consideration soil-pile interaction evaluation resulting from movement soil surrounding pile. This paper presents results three-dimensional finite difference analyses conducted understand effect seismic perfor...

In this paper, numerical analysis of a pile-soil interaction problem is presented considering the parameters influencing the axial load-deformation behavior of the pile embedded in a layered soil medium. The analysis is demonstrated with parametric solutions of a pile with underlain model soil strata under the axial force. An attempt is made to ascertain the extent of influence of elastic prope...

This study aimed to evaluate the p-y behavior of pile foundations installed in saturated silty sand subject cyclic lateral loading. Model piles were with three relative densities (40%, 70%, 90%), and loads magnitudes repeatedly applied. The model test results revealed that as loading was applied piles, soil around became densified loose (relative density 40%), stiffness curve increased. In cont...

In this paper, the analysis of a numerical study for consolidation short bored pile subjected to axial loads is presented. An short-bored performed using finite element software Abaqus CAE with base procured experimental data in sand media and comparative on Ansys FEA. Three models combination footing system were developed by application incremental load which displacement upon each was analyze...
