This article discusses the connection of a steel sheet pile to an I-beam by welding increase horizontal load-bearing capacity. The is checked during experimental study for axial tension. Deformations at reference and maximum loads, as well stresses in weld metal metal, are recorded. During tests, bearing capacity welded joints was confirmed, data on plastic deformations walls under various load...

The ultimate axial bearing capacity (UABC) of a single pile is an important parameter in design. BP neural network (BPNN) has strong nonlinear mapping ability and can effectively predict the UABC pile. However, frequent immersion unstable search results with local vibration leads BPNN to less usable solution. weights biases model are optimized using improved radial movement optimization (IRMO) ...

This study presented a framework for uncertainty analysis of the ultimate axial bearing capacity piles evaluated by UniCone method in layered soils. The Eslami and Fellenius (1997) is direct piezocone penetration test (CPTU) evaluating reliability design. spatial variability CPTU data modeled as random field each soil unit strata. empirical correlation coefficients are assumed to follow lognorm...

In recent years, determining bearing capacity of piles from in-situ testing data as a complement to static and dynamic analysis has been used by geotechnical engineers. In this paper, different approaches for estimating bearing capacity of piles from SPT data are studied and compared. A new method based on N value from SPT is presented. Data averaging, &#10failure zone and plunging failure of p...

Dynamic analysis of a pile embedded in a half-space soil covered by a water layer is crucial for the designs of the pile foundations for bridges, docks and offshore platforms etc. In this paper, a coupled boundary element method (BEM) model is developed to evaluate the dynamic response of the pile. In the proposed model, the pile and half-space soil are treated as elastic media, while the water...

The results of a comprehensive pile load-test program and observations from field monitoring of helical piles with either a single helix or double helixes installed in oil sand are presented in this paper. Eleven full-scale pile load tests were carried out including axial compression, uplift, and lateral load tests. The results of the full-scale load tests are used to develop a theoretical desi...

Urban development in congested cities requires a better exploitation of the available surface, leading to taller structures. These buildings are usually founded on piles that have be increased dimension accommodate larger loads, resulting increases both cost and carbon dioxide footprint pile foundation. An alternative option is improve performance by enhancing shaft capacity, which commonly mos...

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...
