چکیده
A method for computing slip-line fields in the case of cohesionless backfills with stress discontinuity was proposed. The potential failure zone is divided into Rankine and transition zone, rigorously determined using theory plastic mechanics. are then further a series triangular slices. On basis force moment equilibrium conditions typical slice, recurrence equation lateral established. Furthermore, relationship between surface inclination angle interslice established by satisfying Mohr–Coulomb criterion. An iterative procedure calculating slices changing performed until satisfies condition boundary, resulting line if intersect intersection characteristics discontinuity. Example studies to verify present method, which shows that soil–wall interface friction has most significant effect on discontinuity, location gradually approaches backfill an increase retaining wall inclination.

Stress Distribution in a Cohesionless Backfill Poured in a Silo
The field of infrastructure rehabilitation and development requires a better understanding of soil-structure interactions. The interaction behaviour between soil and structures has mostly been investigated through theoretical and/or numerical analysis. This paper presents a series of experiments performed on an intermediate-scale physical model made of an instrumented silo. In contrast to most ...
متن کاملA Novel Method for VANET Improvement using Cloud Computing
In this paper, we present a novel algorithm for VANET using cloud computing. We accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. Each car or node is considered a Client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...
متن کاملLINE-SEGMENTS CRITICAL SLIP SURFACE IN EARTH SLOPES USING AN OPTIMIZATION METHOD
In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...
