with the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. during excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...

It is known that the distribution of active earth pressure against a translating rigid wall is not triangular but nonlinear, owing to arching effects in the backfill. In the present paper, a new formulation is proposed for calculating the active earth pressure on a rigid retaining wall undergoing horizontal translation. It takes into account the arching effects that occur in the backfill (or re...

Abstract— In this paper, an effort has been made to determine the active earth pressure on rigid retaining wall considering non-linear failure surface. The backfill of c-Φ nature has been considered for the purpose. Analytical solutions have been obtained considering non-linearity of the rupture surface using Horizontal Slicing Method. The nonlinear model is supposed to provide more general sol...

In this paper, the problem of a retaining wall under active translation mode is investigated numerically. To this end, a series of numerical models is conducted using the discrete element code, PFC2D. The backfill soil is simulated by an assembly of separate cohesionless circular particles. Backfill soil was prepared by pouring soil particles from a specific height under gravity force and givin...

Simulations de grandes déformations et post-rupture des murs de soutènement segmentaires utilisant la méthode des mailles-libres (SPH) ABSTRACT: Numerical methods are extremely useful in gaining insights into the behaviour of reinforced soil retaining walls. However, traditional numerical approaches such as limit equilibrium or finite element methods are unable to simulate large deformation and...

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 ana...
