Behavior of foundation piles resisting lateral forces in soft soil

Experimental Load Transfer of Piles Subject to Lateral Soil Movement

Remediation of slope failures requires stabilization alternatives that address causes of slope instability. Slope reinforcement and pile stabilization systems, if properly designed, are effective in preventing slope movements in weak soils. Soil load transfer to pile elements from the lateral soil movement as occurs in slope failures is a complex soil-structure interaction problem, and the sign...

Predicting ε50 for Lateral Behavior of Piles in Marine Clay Using an Evolutionary Based Approach

Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...

Composite piled raft foundation with intermediate cushion in layered soil under seismic forces

In order to mobilize shallow soil to participate in the interaction of piled raft foundation sufficiently, the concept of piled raft has been modified to new type of foundation named composite piled raft. In the system of composite piled raft, the short piles made of flexible materials is used to strengthen the shallow soft soil, while the long piles made of relatively rigid materials is used t...

Internal Forces in Piles “Under External Forces and Earthquake in Homogeneous and Nonhomogeneous Media”

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....
