Seismic Bearing Capacity of Piles in Liquefiable Soils

Dynamic Stiffness of Piles in Liquefiable Soils

buckling behavior of piles in liquefiable soils

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...

Lateral Bearing Capacity of Piles in Cohesive Soils Based on Soils' Failure Strength Control

This paper presents the results of a series of numerical analysis carried out on piles in cohesive soils. Broms (1964a) proposed graphs to obtain ultimate lateral bearing capacity of such piles. However, the graphs do not cover all piles with different lengths. In this study, a finite difference program that is especially designed for piles is used. The investigations were carried out by varyin...

Seismic response of end-bearing single piles

A numerical study is presented of the dynamic response of end-bearing piles embedded in a number of idealized soil deposits and subjected to vertically propagating harmonic S-waves. Results, for both 'kinematic' and 'inertial' interaction, are offered in the form of dimensionless graphs and formulae covering a wide range of excitation frequencies and of crucial material and geometric parameters...

Evaluation of seismic performance of pile-supported models in liquefiable soils

The seismic performance of four pile-supported models is studied for two conditions: (i) transient to full liquefaction condition, i.e. the phase when excess pore pressure gradually increases during the shaking; (ii) full liquefaction condition, i.e. defined as the state where the seismically induced excess pore pressure equalises to the overburden stress. The paper describes two complementary ...
