This paper presents novel measurement data on the dynamic soil–structure interaction of an end-bearing pile foundation. The purpose is to assess ability predict foundation impedances based small-strain properties soil obtained from site investigations. Measurements were performed in two stages construction, allowing between piles through soil. First, single and factors experimentally for four w...

The present study investigates the effect of de-sanding (recycling system) on bearing capacity bored piles. Full-scale models were conducted two groups piles, first group was implemented without using this system, and second recycling system. All piles tested by static load test, considering time factor for which implemented. test results indicated a significant clear difference in when use sys...

A macroscopic elastic description of stresses in static, preloaded granular media is derived systematically from the microscopic elasticity of individual inter-grain contacts. The assumed preloaded state and friction at contacts ensure that the network of inter-grain contacts is not altered by small perturbations. The texture of this network, set by the preparation of the system, is encoded in ...

Recently, have been applied widely in infrastructure Indonesiam especially if the new building was built around another building. Therefore, bore pile is considered most suitable for this case. In research, which ere previously existing condition as group drilled piles were modified into single pile. The result of study indicate that use borepile very safe terms bearing capacity, deflection and...

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...

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...

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...

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 ...
