Design Diagrams for the Analysis of Active Pressure on Retaining Walls with the Effect of Line Surcharge

Abstract

In this study, a formulation has been proposed to calculate the pressure on wall and determine the angle of failure wedge based on limit equilibrium method. The mentioned formulation is capable of calculating active pressure coefficient, culmination of forces in failure surface, and pressure distribution on wall with the effect of line surcharge. In addition, based on the proposed method, a simple formula has been proposed to calculate the angle of failure wedge by the effect of surcharge. Moreover, the proposed approach has the advantage of taking into account the effect of surcharge on elastoplastic environment by considering the parameters of soil and determining the extent to which the surcharge is effective in pressure distribution on the wall. However, in most previous methods and specifications, resultant lateral pressure from surcharge in elastic environment had been considered. Finally, based on the obtained results, the design diagrams for different soils and different surcharges have been proposed. According to these diagrams, pressure on wall, pressure distribution on wall, and angle of failure wedge will easily be achieved. Also, a computer program has been written in MATLAB software environment. Using the results of these codes, the pressure on wall with the effect of surcharge, the angle of failure wedge, and pressure distribution on wall will be determined.

Strength Analysis of Soil Retaining Wall Using Numerical Method of Manokwari Landfill

“…Several designs of retaining walls that have been widely used include Gravity Retaining walls [2,[7][8][9][10][11][12], Cantilever Retaining walls [8], Counter fort Retaining walls [3,8,[13][14][15][16][17][18], Reinforced Soil Retaining walls [5,6,8,[19][20][21][22][23][24][25], and anchored bulkhead [8,19]. Along with its development, the retaining wall design has been added according to applications including the Gravity Retaining wall design [4,16,19,[26][27][28] and Counter fort Retaining wall [19,29].…”

“…General rules, retaining walls are distinguished by the material used, the load transfer method, workload, and production technology [19]. In constructing a retaining wall, the most important thing is to know the active ground pressure [2,7,9,10,13], the seismic pressure [3], the passive soil pressure [6,[20][21][22], the active soil pressure [23,26], static and dynamic soil pressure [4], and lateral pressure [5].…”
