An alternative mechanism of pile failure in liquefiable deposits during earthquakes
نویسندگان
چکیده
This paper proposes an alternative mechanism of pile failure in liquefiable deposits during earthquakes. This failure mechanism, based on pile buckling, is formulated by back-analysing 14 case histories of pile foundation performance during earthquakes and verified using dynamic centrifuge tests. A new parameter, the slenderness ratio of a pile, is introduced to classify pile performance in liquefiable soils. This parameter fits very well both the reported case histories and the centrifuge test results.

Pushover Analysis of Piles in Stratified Soil
Pile foundations have been the subject of interest for earthquake engineers since last several decades. The devastations caused in major earthquakes of the world can be the reason enough to carry out the research on the topic of seismic behavior of piles. One definite concern is liquefaction induced ground movement after the shaking in an earthquake, causing extra lateral loads acting on piles....
متن کاملNumerical simulation of liquefaction susceptibility of soil interacting by single pile
Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...
متن کاملEvaluation of uniform delivery of colloidal nano-Silica stabilizer to liquefiable silty sands
Liquefaction is one of the most important and complex topics in geotechnical earthquake engineering. In recent years, passive site stabilization method has been proposed for non-disruptive mitigation of liquefaction risk at developed sites susceptible to liquefaction using colloidal nano-silica stabilizer. In this research, 4 box models were used to investigate the ability to uniformly deliver ...

متن کاملSeismic Retrofit of Pile Group Foundation with Thickened Caps
The case studied in the paper proves that thickening the pile cap is an effective seismic retrofit alternative to strengthen a pile group foundation. Unlike the typical seismic retrofitting of foundation, the proposed method eliminates the need to drive long piles into existing bridge substructures, substantially reducing cost, construction time and traffic interruption. The method thickens the...
