Numerical Analysis of Shallow Foundations with Varying Loading and Soil Conditions

چکیده
The load–deformation relationship under the footing is essential for foundation design. Shallow foundations are subjected to changes in hydrological conditions such as rainfall and drought, affecting their saturation level conditions. actual load–settlement response design reconstructions determined experimentally, numerically, or utilizing both approaches. Ssettlement computation performed through large-scale physical modeling extensive laboratory testing. It expensive, labor intensive, time consuming. This study carried out determine effect of different degrees loading on settlement shallow using numerical Plaxis 2D, Bentley Systems, Exton, Pennsylvania, US. Plastic was used dry soil calculation, while fully coupled flow deformation partially saturated soil. Pore pressure were computed deformation. Mohr–Columb model simulation, parameters calculated from experimental results. results show that degree more critical than When a 200 KPa load applied at center footing, recored 28.81 mm, which less 42.96 mm case full-depth shale layer; therefore, reduced by 30% underlying limestone rock layer.

A Numerical Evaluation of Seismic Response of Shallow Soil Deposits
This paper employs one-dimensional numerical ground response analysis models to investigate seismic response of shallow cohesive and non-cohesive soil deposits on vertical propagation of horizontal shear waves. Soil response is modelled by traditional equivalent-linear (EL) frequency-domain analysis using DEEPSOIL software and nonlinear (NL) time-domain analysis using OPENSEES software. The ana...
متن کاملSoil-Structure Interaction of Buried Pipes Under Cyclic Loading Conditions
The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...
