The anti-slide pile is one of the most used measures in landslide control globally. Following its application, various structures have been developed. In this paper, we analyze structure development process and extract two paths. One path aimed at improving applicability. second starts from an in-depth study pile–soil interactions. However, these paths share a single design concept: provides di...

The principal objective of this thesis is to assess the capabilities of an already established analytical framework for understanding and predicting the behavior of piles driven in highly overconsolidated clays (OCR24). The skin friction mobilized during pile loading to failure depends on the sequence of preceding events, i.e. pile installation and soil consolidation. This research utilizes the...

This paper presents a methodology to understand the interface behavior of soil and pile under transient loading. Previous works by Trochanis (1991), Bently and Naggar (2000) and others gave an insight to the problem. But this paper illustrates the research methodology developed to understand the dynamic behavior of pile and soil by taking the soil yielding effects and also the interface effects...

Three case studies involving the use of numerical models are presented in this paper. First, a comparison of FE modelling of a deep excavation is made using 2-D finite element software, SAGE-CRISP and PLAXIS. In the second study, benchmarking is made between results obtained from 2-D FE modelling using PLAXIS and well-established 3-D centrifuge studies for the case of an existing single pile an...

In order to satisfactorily reproduce the Soil-Structure Interaction (SSI) effects under earthquake loading, it is often necessary to model a large domain of the soil surrounding the structure of interest. High spatial/temporal resolution is another challenge in analyzing these models. A new parallel nonlinear finite element program, ParCYCLIC, is employed to study such high fidelity large-scale...

We numerically study the piles generated by continuously dropping a particle on the top of a stable pile in (I + I) dimension. We use a code which has an implementation of static friction in the Molecular Dynamics (MD) simulations of granular material. We study several properties of the pile-the time evolution of mass and slope, and the avalanche size (and duration) distribution. We also study ...

The temporal fluctuation of the average slope of a ricepile model is investigated. It is found that the power spectrum S(f) scales as 1/f with α ≈ 1.3 when grains of rice are added only to one end of the pile. If grains are randomly added to the pile, the power spectrum exhibits 1/f behavior. The profile fluctuations of the pile under different driving mechanisms are also discussed. PACS number...

The potential effects of pile driving on fish populations and commercial fisheries have received significant attention given the prevalence of pile driving occurring in coastal habitats throughout the world. Behavioral impacts of sound generated from these activities on fish typically have a greater area of influence than physical injury, and may therefore adversely affect a greater portion of ...

Deep foundations are slender pile elements used to transfer loads from structures into deeper soil strata below the ground. Deep foundations have a variety of loads including axial, lateral and moments. Often these loads will act together to form a combination of loads, such as oblique forces that have a component of axial and lateral forces. Due to the pile’s length, which can extend past 30 m...

We study a variation of the combinatorial game of 2-pile Nim. Move as in 2-pile Nim but with the following constraint: Provided the previous player has just removed say x > 0 tokens from the pile with less tokens, the next player may remove x tokens from the pile with more tokens. But for each move, in “a strict sequence of previous player next player moves”, such an imitation takes place, the ...
