Isostaticity and Mechanical Response of Two-Dimensional Granular Piles

open access: yes, 2004
We numerically study the static structure and the mechanical response of two-dimensional granular piles. The piles consist of polydisperse disks with and without friction.

Effects of axial loads and soil density on pile group subjected to triangular soil movement [PDF]

open access: yes, 2017
Laboratory tests have been carried out to investigate the response of 2x2 pile group subjected to triangular soil movement. The pile group was instrumented with displacement and tilting devices at the pile cap and strain gauges on two piles of the group.

The Impact of Different Excavation Support Structures on the Deformation and Stability of Adjacent Station and Tunnels

open access: yesBuildings
This study uses the finite element software Midas GTS NX (2019), combined with actual engineering projects, to establish numerical models and analyze the impact of different support types (pile-anchor support and double-row pile support) on the ...

Working Mechanism of Pile Group with Different Pile Spacing in Dense Sand

open access: yesAdvances in Civil Engineering, 2019
Complex interaction mechanism exists between the pile group and soil. To realize the pile-soil load transmission mechanism in detail, the failure pattern of pile groups installed in dense sand considering different pile spacing was investigated by means ...

Transient Response of Float Pile Under Vertical Impact Loading in Unsaturated Soil

open access: yesTaiyuan Ligong Daxue xuebao
[Purposes] On the basis of the dynamic governing equation of three-dimensional porous media, the vertical transient response of float pile in unsaturated soil is analyzed with considering of the coupling effect of liquid and gas phases.

Numerical Modelling of Displacement Pile Resistance in Sand Ground. Part 1: Soil Physical Model, Calibration of Model Parameters

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2021
Accuracy of numerical modelling of ground resistance of the displacement pile highly depends on proper evaluation of its states: prior loading and its changes during the loading.

Mobilization of Mini Pile Uplift Resistance in Sand [PDF]

open access: yes, 2015
Shaft resistance of tension pile will be fully mobilized at certain displacement. Some structures impose limits to the displacement of pile with a relatively small value in order not to cause damage.

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Model tests of large-diameter single pile under horizontal cyclic loading in sand

open access: yesRock and Soil Mechanics, 2021
A series of 1g model tests was carried out using a motor servo horizontal cyclic loading equipment to study the stiffness and cumulative displacement of the large-diameter single pile in sand under horizontal cyclic loading.
