چکیده
in this study, stability of geosynthetic reinforced soil retaining walls investigated using plaxis code that is based on finite element method. the effects of axial stiffness, length and vertical space between geosynthetic layers, internal friction angle of soil wall and cohesion of foundation on deformations of wall and maximum axial force of geosynthetic have been investigated. results of analyses indicated that horizontal displacements and settlements of wall reduce with increase in axial stiffness, length and decrease of vertical space between reinforcement layers but there is a critical value for axial stiffness, length and number of geosynthetic layers which increase more than this certain value has not significant effect on reduction of settlements and horizontal displacements of wall. also vertical and horizontal deformations of wall reduce with increase in internal friction angle of soil wall and cohesion of foundation but effect of these two factors on reduction of deformations for values more than a critical value are almost constant.

Simplified Procedure to Evaluate Earthquake-induced Residual Displacement of Geosynthetic Reinforced Soil Retaining Walls
Based on a series of shaking table model tests, it was found that the eŠects of 1) subsoil and backˆll deformation, 2) failure plane formation in backˆll, and 3) pullout resistance mobilized by the reinforcements on the seismic behaviors of the geosynthetic reinforced soil retaining walls (GRS walls) were signiˆcant. These eŠects cannot be taken into account in the conventional pseudo-static ba...

Out of all methods for ground improvement, stone column became more popular these days due to its simple construction and economic consideration. Installation of stone column especially in loose fine graded soil causes increasing in load bearing capacity and settlement reduction. Encased granular stone columns (EGCs) are commonly subjected to vertical load. However, they may also be subjected t...

متن کاملEvaluation of Geosynthetic Forces in GRSRW under Dynamic Condition
Geosynthetics have proved to be suitable for reinforced soil retaining walls. Based on the increasing uses of geosynthetic reinforced soil systems in the regions, which bear frequent earthquakes, the study of dynamic behavior of structures seems necessary. Determining the reinforcement forces is; therefore, one of the most important and main points of discussions in designing retaining walls, b...
