A Shallow foundation on cohesionless soil cannot support greater weights; piled raft foundations are recommended because they combine the load-bearing qualities of piles and raft. Combined Piled Raft Foundations (CRPF) efficient for tall buildings account both vertical lateral loads. In a pile foundation, raft’s load-resistance is disregarded due to soil-structure interaction. Simplification ma...

The bearing capacity of a single pile in granular soil was analyzed piles under vertical loads in the study of the mechanism of shaft fiiction. The effect of the deformation modulus on the bearing capacity of the single pile in granular materials, and especially in sand, was examined. By using the FLAC program for the finite element analysis it was possible to predict quite accurately the load ...

In this study, based on the actual project in Dalian, dynamic interaction of double tunnel sand bridge pile system (SSSI) under earthquake action is studied by shaking table test, and response laws structure site are obtained, which compared with ABAQUS numerical simulation. The Kelvin constitutive model subprogram introduced into model, equivalent linear method used to deal nonlinear problems ...

The thermal response of an energy field scale pile that is part a pair piles spaced at centre-to-centre distance 3.5 m (i.e., 6D, where D the diameter), was examined experimentally and numerically. Three tests were conducted to assess axial radial responses pile: (i) heating alone, (ii) both simultaneously, (iii) other while considered not heated. Good agreement obtained between experimental nu...

This study presents a multi-effect coupling model to optimize the design of geosynthetic-reinforced pile-supported embankment (GRPSE) considering effects soil arching, membranes, and pile–soil interaction on coastal highway. The developed could GRPSE fulfill construction requirements at relatively low project cost. was achieved by adjusting critical factors that govern settlement GRPSEs, such a...

We simulate static model sandpiles in two dimensions (2D) and focus on the stresses inside the pile. In this study tangential forces, e.g. friction, are neglected. We compare the simplest possible interaction model, i.e. a linear spring and a linear dashpot, with a nonlinear law based on Hertz' theory. Furthermore, we present data obtained by a simulation of frictionless polygons with twelve si...

For the discrete model suggested by Lorenz in 1996 a one-dimensional long wave approximation with nonlinear excitation and diffusion is derived. The model is energy conserving but nonHamiltonian. In a low order truncation weak external forcing of the zonal mean flow induces avalanche-like breather solutions which cause reversal of the mean flow by a wave-mean flow interaction. The mechanism is ...
