Helical piles are foundation systems used to support compression, tension, and lateral loads. However, this type of was around the world for more than 25 years. Its behavior, especially in Iraq, is still unknown scare. The present study carried out by analyses pile using finite element method. Modeling helical geometry has been proposed through computer program Plaxis 3D. Parametric were also p...

Based on the strength reduction method, laws of slope displacement and changing positions sliding surface during filling process are studied. The model multistage fill is established by finite element software PLAXIS. difference compared between with no reinforcement under same working condition. Sensitivity analysis carried out from two aspects which internal factors external factors. shows th...

The damage of tunnel induced by intense earthquake is obviously important. Thus, more attention has been paid to the destruction earthquake. So far, there are few studies conducted on influence dynamic loads horizontal twin tunnels. In this research, a systematic analysis tunnels Cairo Metro Line No. 4 was performed using finite element model commercial software PLAXIS 2D and under static Dahso...

Abstract Axisymmetric solutions for the bearing capacity of ring foundation resting on anisotropic and heterogenous clays are presented in this paper using finite element analysis (FEA). The NGI-ADP model PLAXIS FEA, a widely used soil model, is adopted to study stability responses foundations, with special consideration given effects increasing undrained shear strength depth. Numerical results...

The main purpose of the examination roads is timely identification areas that require improvement road conditions, as well evaluation state all structural elements roads. study causes deformations, measures to eliminate and prevent warping are issue maintenance. survey was conducted in accordance with approved methods using standard measuring tools. PLAXIS software used perform finite element a...

Aiming at the problem of insufficient research on action mechanism and stability calculation method top beam in pile-anchor support structure, firstly force deformation model are established based elastic fulcrum coordination principle structure pile anchor end this paper. Secondly, under synergy crown simplified internal force, displacement overall slope constructed. Finally, combined with an ...

The article discusses the features of monitoring enclosing structures deep excavation, made using technology a diaphragm wall in ground. In modern geotechnical construction practice, it is important to ensure safe execution works on installation pits built-up part city. use for fencing pit has become popular technical solution. However, there are many uncertainties associated with work construc...

Abstract One of the crucial factors that has gained widespread popularity during tunnelling construction process is face stability tunnel mainly depends upon support pressure to be applied at against overburden and surcharge loading acting on earth surface. In this study, different cross sections tunnels been investigated in cohesionless soil (loose medium dense sand) using Finite Element Analy...

In this paper, a modified shear strength reduction method (MSSR) and its optimization variant (OPT-MSSR) are suggested. The idea of MSSR is to approximate the standard be more stable rigorous from numerical point view. consists simplified associated elasto-plastic model completed by depending on dilatancy angle. Three Davis' modifications suggested Tschuchnigg et al. (2015) interpreted as speci...
