S: A series of centrifuge model tests were performed to assess the tunneling-induced ground deformations and their detrimental effects on the neighboring single pile in the saturated sandy ground. The relative elevations between the pile tip and the buried depth of new driven tunnel dominated the distributions of bending moment and axial force along the depths. A load transfer mechanism is prop...

This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...

Analytical solutions are developed for harmonic wave propagation in an axially or laterally oscillating pile embedded in homogeneous soil and excited at the top. Pilesoil interaction is realistically represented through a dynamic Winkler model, the springs and dashpots of which are given values based on results of finite element analyses with the soil treated as a linear hysteretic continuum. C...

Received: June 12, 2017 Revised: October 24, 2017 Accepted: November 03, 2017 Abstract: Background and Objective: Prestressed high strength concrete pipe pile (PHC) shows brittle fracture when subjected to more than its own bearing capacity. Therefore, the non-prestressed steel bar is added to the PHC pipe pile, that is, the mixed reinforced pipe pile (PRC). The mechanical behavior of PRC group...

This study focuses on the finite element simulation of piles with different models in sandy soils using software PLAXIS 3D V20. The parametric has conducted to investigate influence multiple parameters axial capacity steel soil, including cross-section variables two cases: open and close-ended piles. typical circular square were selected as reference for comparison open-ended tapered pile 3b sh...

Pulsed power technology and appropriate boundary conditions have been used to create simulations of magnetically driven astrophysical jets in a laboratory experiment. The experiments are quite reproducible and involve a distinct sequence. Eight initial flux tubes, corresponding to eight gas injection locations, merge to form the jet which lengthens, collimates, and eventually kinks. A model dev...

this research examines the behavior of soil-reinforced piles and applied loads based on the analytical method and by using the numerical results of flac3d software for comparison with the analytical results. the analysis was based on a method called virtual retaining wall, the following into consideration: an imaginary retaining wall that passes the footing edge the bearing capacity of footing ...

One of the most important structures in the ports is the wharf. The most common one is the pile-supported wharf. This type of wharf is consisted of a number of piles and one deck which placed on the piles. In addition to the conventional loads that this structure should withstand, in seismic areas, pile-supported wharfs should have the necessary capacity and strength against seismic excitations...
