In this paper, a numerical investigation of the effects grout parameters on load response concrete pile-grout systems in soft clay is presented. The study examines influence diameter and depth bearing capacity pile under vertical lateral loads. research findings indicate that grouting can enhance single system by up to 27% loads 51% loads, depending used. This due grout's ability fill voids soi...

Simple methods of analysis are developed for computing the dynamic steady-state axial response of floating pile groups embedded in homogeneous and non-homogeneous soil deposits. Physically-motivated approximations are introduced to account for the interaction between two individual piles. It is found that such an interaction arises chiefly from the ‘interference’ of wave fields originating alon...

An overview of offshore wind turbine (OWT) foundations is presented, focusing primarily on the monopile foundation. The uncertainty in offshore soil conditions as well as random wind and wave loading is currently treated with a deterministic design procedure, though some standards allow engineers to use a probability-based approach. Laterally loaded monopile foundations are typically designed u...

The performance of the analogue signal processing filter implemented in the front-end readout chip for the CMS Micro Strip Gas Chambers is evaluated for tracks with incidence angle up to 45 degrees. The impact on efficiency, bunch crossing pile-up and signal to noise is quantified using Monte Carlo generated events simulating isolated hits in MSGC modules described according to the CMS baseline...

Pile foundations are relatively vulnerable to lateral loads. During liquefaction-induced lateral spreading, this vulnerability is particularly conspicuous due to a loss of strength and stiffness in the liquefied soil. A nonlinear effective stress analysis incorporating an elastoplastic constitutive model based on Finite Difference Method (FLAC2D program) was used to numerically simulate shake t...

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...

Reducing the settlements of soft foundation effectively is a critical problem of high-speed railway construction in China. The new CFG pile-slab structure composite foundation is a ground treatment technique which is applied on CFG pile foundation and pile-slab structure composite foundation. Based on the experience of constructing Beijing-Shanghai high-speed railway in China, the settlement-co...

We demonstrate highly parallelized fluorescence scanning microscopy using a refractive microlens array. Fluorescent beads and rat femur tissue are imaged over a 5.5 mm x 5.5 mm field of view at a pixel throughput of up to 4 megapixels/s and a resolution of 706 nm. We also demonstrate the ability to extract different perspective views of a pile of microspheres.

A vertical electro-osmosis method was proposed to improve the bearing capacity of piles in marine soft clay foundations. top-down test conducted by setting an anode and cathode at top bottom pile, respectively, while settings bottom-up were set opposite way. At same time, a pile without also up for comparison. The variation law water content, discharge volume, soil pressure, surface settlement ...

The introduction of controlled gradients in plastic properties is known to influence the resistance to damage and cracking at contact surfaces in many tribological applications. In order to assess potentially beneficial effects of plastic property gradients in tribological applications, it is essential first to develop a comprehensive and quantitative understanding of the effects of yield stren...
