In order to compare and analyze the seismic response characteristics of a safety-related nuclear structure on non-rock site in condition raft pile group foundations under unidirectional multidirectional motion input, large-scale shaking table test soil-nuclear system was carried out this paper. test, soil uniform silted clay, shear wave velocity 213 m/s. Considering similarity superstructure na...

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...

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 ...

To accommodate the shear requirement and settlement of high rise construction, concept piled-raft foundation has been developed. This research deals with successive analysis parameters system using PLAXIS-2D as a FEM tool. Plain strain piled raft conducted out by fixing up parameters. For two cases studied for lying on silty soil deposit clayey respect to uniform static loading from superstruct...

The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...
