The dynamic responses of pile–liquefied composite soils are complex, and the bearing capacities single piles or pile groups in liquefiable remain unclear. For friction piles, resistance determines vertical capacity pile. In a pile–soil system, it is very important to study changes during vibration. Based on shaking table test, this investigated foundation–liquefied soil system under simulated h...

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

New and existing components of retaining structures are often combined in the width section. When combining design use requirements new structures, synergistic interactions between working conditions require clarification. In conjunction with an actual project, a sheet pile wall consisting is proposed to retain embankment. Indoor model tests were carried out simulate excavation compaction inves...

in the realistic manner, piles are similar to the slender columns that soil around them acts as a lateral support. the piles situated in the liquefiable soil layers, loss their lateral supports due to the liquefaction resulted from the seismic ground motion. in this case, pile has the potency of axial instability similar to the unsupported columns. this instability can lead to the lateral buckl...

A field pile loading test was carried out on the Peshawar–Karachi Motorway (PKM) project in Pakistan to show settling mechanism of bored foundation pulverized soil and force characteristics frictional resistance at pile-soil interface. The changes lateral settlement during loading-unloading process piles were measured analyzed, as well load-settlement distribution different layers, internal for...

background: monitoring of indicator and pathogenic microorganisms is essential for proper composting. the aim of this study was to evaluate the change in population of coliform bacteria and salmonella spp. in composting process of municipal wastes and after its application on soil. methods: the samples were taken from each raw waste pile, initial pile, and active phase pile, cooling phase pile ...

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...

Offshore wind energy development is driven by ongoing research and to determine technological issues connected with offshore turbines. A fundamental design difficulty the turbine foundations. By far, one of most commonly practiced foundation systems mono helical pile foundations because their simplicity resilience. Most studies on piles were focused granular soils few clayey soils. However, in ...
