Abstract: According to the Winkler assumption, the form of the pile constraint could be simplified as bottom fixing and top free. Considering the influence from resistance of soil around pile, the equations on calculated length for buckling stability of steel pipe pile when the portions along the pile length were constrained in the uniform foundation and the layered foundation were respectively...

A pile foundation with ground improvement under the footing is a composite objectives of enhancing seismic performance and rationalizing substructure by combining improvement. Although effectiveness this method has been confirmed in previous studies for application to soft grounds, applicability liquefiable grounds yet be fully investigated. In study, therefore, centrifuge model tests finite el...

Tunnels and foundation pits are two separate types of excavation that frequently used in urban settings. Excavating tunnels sequentially around existing pile foundations is becoming more prevalent as underground space utilization rates increase. The deformation load transfer mechanisms the group under asymmetric conditions “first tunnel, then pit” pit, tunnel” studied from perspective relative ...

The settlement of a group pile foundation is the result elastic-plastic and rheological soil. Unfortunately, most research only considers elasto-plasticity piles or soils. Classical theories like Poynting-Thompson model provide some prediction for behavior groups, which cannot satisfactorily reflect total characteristics foundation. In current paper, we presented method to study behaviors in li...

Pile driveability analyses for offshore platforms require a unique set of criteria, which may not normally be associated with other pile foundation installations. The selected hammers, pile makeup details and soil profile must be carefully reviewed, as these factors will determine if pile installations will be successful. The most important of the variables to establish is the expected Soil Res...

ABSTRACT This study presents an investigation of the interaction effect of one loaded pile on a neighboring pile under transient dynamic loadings. Analyses are carried for non homogeneous soils. The hybrid boundary element formulation is used to represent boundary integral representation of soil domain and pile equations represented by linear structural components. The formulation is presented ...
