There is a growing demand for multi-story buildings residence and commercial purposes in coastal areas of Sindh, Pakistan. Such types soils are generally considered more compressible with high groundwater levels, which may cause lower shear strength higher settlement. The computation the settlement foundations requires use advanced constitutive models, not commonly used due to lack field or exp...

In a combined piled raft foundation (CPRF) both and piles take their share of the total load applied. However, in practice, contribution taking is usually ignored assumed to be supported on piles. This way CPRF becomes excessively conservative uneconomical. To economize design, relative sharing has found. this connection, different simplified methods have been developed, each one with some limi...

This paper presents the experimental analysis that was conducted on small-scale 1g physical models of piled raft foundation structures with a group 2 × piles in loose sand. The purpose to reduce settlement raft. test program included twelve experiments, three which were alone and nine rafts at pile distances 3d, 4d, 5d lengths 10d, 20d, 40d, where d is diameter. results show current conventiona...

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...

In order to get a more safety and economic foundation, finite element method was performed for piled mat cap strip by the software of STAAD. Through analysis, plate distribution region bending moment shear stress were researched; meanwhile, considering compatibility deformation plate, how chose design value researched. The result showed that: single is not representative, average 9 plates (3x3 ...

The use of embedded pile elements provides a convenient approach that may save significant modelling time in the simulation of piled foundations. A back-analysis of an Osterberg-cell (O-Cell) load test on a 45 m long pile is presented to illustrate some of the advantages of using structural embedded elements. Comparisons with other modelling approaches for piled-raft foundations have showed goo...

Large-scale model tests were established at a scale of 1/5 using 7 m deep tank with cross-sectional dimension 5 × 4 m, to study the vibration response characteristics ballastless track, embankment, and X-section piled raft foundation under cyclic axial load, including displacement, velocity, dynamic soil, pile stress. Cyclic loading can be achieved by controlling frequency cycles through servo ...
