Abstract In the present study, a small piled raft foundation has been simulated numerically through PLAXIS 3-D software. The objective of this study was to investigate effect governing parameters such as pile length, spacing, diameter, and number piles on settlement load-bearing behavior raft, so achieve optimum design for configurations. An optimized is defined with allowable center differenti...

This paper introduces an experimental research on the behavior of piled raft foundation (PRF) in sand two states (loose and medium sand). A small model has been tested a soil container vertical load was applied to through pneumatic jack. The settlement measured using displacement transducer; three sensors were attached pile heads measure axial borne group by each Arduino data logger. laboratory...

The stiffness and damping of pile foundations are proposed, which vary with the ratio of shear modulus Gi / Go to indicate the nonlinear properties of soil. The range of Gi / Go is defined with different vibration intensities for applications, and a computer program DYNAN is available based on the boundary zone model with non-reflective interface. Two engineering cases are studied to illustrate...

1.1 Offshore Structures: Offshore structures used for oil and gas extraction have the common function of providing a safe, dry working environment for the equipment and persons those operates the platform. Jacket supported drilling equipment as a guide for the piled foundations. The substructure referred to as the jacket is a three dimensional space frame made from large tubular steel members. ...

Abstract The micropiled raft offers a foundation system that combines the advantages of conventional piled and efficient installation micropiles. In this paper, comprehensive numerical analysis was conducted on behavior rafts under combined vertical lateral loading using finite element modeling. A model calibrated against full-scale axial field tests is used to conduct analysis. soil profile so...
