Rock-socketed pile is widely used in coastal wharf, Marine bridge, and power engineering, the end bearing function considered more design process. However, lateral friction resistance of rock-socketed piles an important part, load transfer mechanism pile–soft rock interface research focus. In this paper, a comparative analysis was adopted test, ten groups test specimens were made, including fiv...

A 2-d dislocation pile-up model is developed to solve problems with arrays of edge dislocations on one or multiple slip planes. The model developed in this work has four unique features: 1) As a continuum mechanics model, it captures the discrete behaviors of dislocations including the region near pile-up boundaries. 2) It allows for a general distribution of dislocations and applied boundary c...

Pathogen contamination of waterways is a serious concern in dairy farming areas where livestock waste is applied to agricultural fields. As an alternative, a biodrying composting system dries collected livestock waste, reduces the strong odors, and has been proposed as a means of reducing, and even eliminating pathogens present in the waste. Therefore, the survival of pathogens in a biodrying c...

This paper presents 53 well-documented cases of the short-term set-up of open-ended steel pipe piles driven at two fields in the North Sea. Increases in soil resistance during driving (set-up) were observed when pile driving was re-started after delays typically ranging between 24 h and 100 h. The soil encountered at the sites consisted of overconsolidated sands and clays, where the clays varie...

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 ...

The effects and vertical bearing capacity of two jacked piles in sand are still not well understood, the mechanism adjacent pile’s uplift caused by jacking pile a double system is especially unclear, but these facets important to stability pile. In this paper, series tests performed on model sand, where influences length driving speed were studied. results revealed that mainly relation influenc...

There is significant interaction between the new supporting structure and existing adjacent retaining wall in dredging excavation project of urban rivers. In addition, three factors, spatial location, stiffness structures, soil conditions two sides will exert effects on bearing properties structures. Combined with an actual project, FLAC3D software was applied to analyze influencing rule U-shap...

In order to study pressed pile test and ultimate bearing capacity character of large-diameter steel pipe pile, based on two high-piled wharfs of Zhanjiang Port, pressed pile test and numerical simulation of three large-diameter steel pipe piles are analyzed in this paper. Anchored pile method is used to pressed pile test, and the curves of Q-s and ultimate bearing capacity are attained. Then th...

We show that the one-dimensional Oslo rice-pile model is a special case of the abelian distributed processors model. The exact steady state of the model is determined. We show that the time evolution operator W for the system satisfies the equation Wn+1 = Wn where n = L(L + 1)/2 for a pile with L sites. This is used to prove that W has only one eigenvalue 1 corresponding to the steady state, an...
