The integrity of cast-in-place foundation piles is a major concern in geotechnical engineering. In this study, distributed fibre optic sensing (DFOS) cables, embedded in a pile during concreting, are used to measure the changes in concrete curing temperature profile to infer concrete cover thickness through modelling of heat transfer processes within the concrete and adjacent ground. A field tr...

At present, reducing subgrade settlement of soft soil foundation is a key problem in high-speed railway construction. Pile-slab structure is a widely-utilized form of foundation structure to reduce the subgrade settlement in China. In order to save the engineering cost for high-speed railway construction in developing countries, the author developed a pile-slab structure and named it as the new...

stable pile depth in the Snowy River study (SKM 2005) is outlined. The inputs used in the run of the LLP99 model were: • single soil layer, • very high flexural stiffness of pile (1,000,000 kN/m). • pile width = 0.3 m (i.e. wooden pile), • shear strength in the absence of lateral stress (for unconsolidated sand 150 kN/m was used), • effective unit weight of soil (15 kN/m), • active lateral effe...

The present study compared the performance of soldier pile and concrete bearing pad anchored wall facings. Using Abaqus finite element software, two case studies have been precisely represented for the facing designs and effects of the parameters of soil type, spacing of anchors and facings, surcharge and facing sizes were investigated. The analysis results indicate that the soldier pile method...

this paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

in this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. in the created model, both pile and surrounding soil are modeled using fiber elements in a practical beam on nonlinear winkler foundation (bnwf) concept. herein, the features of drain–3dx finite element software are ...

In many real applications, sorting plays an important role as it makes easy to handle the data by arranging it in ascending or descending order, according to requirements. Bubble sort is most common sorting algorithm, but not efficient for many applications. There are number of other sorting algorithms and still, research is going for new sorting algorithms to improve the complexities of existi...

The emergence of stacks as a hardware device in stack machines implies the recognition of the importance of using stacks in different computer applications and the need to make use of them in others. This paper uses stacks to solve the sorting problem. Two stack-based sorting algorithms are introduced. The first is based upon sorting by the insertion technique, whereas the second is based upon ...

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 ...
