METHODOLOGY FOR CALCULATING THE STABILITY OF THE GABION RETAINING WALL ACCORDING TO EUROCODE 7

Abstract

The methodology of calculating the stability of gabion retaining walls according to Eurocode 7 is explained in the paper. The calculation of the gabion wall is done according to Eurocode 7, within which 3 project approaches are defined according to the bearing capacity limit states (STR+GEO). The calculation of the stability of the gabion wall is done according to the design approach 2 *, when partial coefficients are applied to forces and resistances, but only at the end of the calculation, so that it, for the most part, takes place using characteristic values, as it was our practice. A solution in form of a gabion wall was given on the road section Kosjerić - Požega, regarding the chainage from km 183 + 075 to km 205 + 210 (22. 135 km long), due to the designed road widening and the designed footway in the area of the intersection Kosjerić (railway station) and due to lack of space to make an embankment, in the area of the bottom of the embankment on the right side of the road. Based on soil testing, the parameters required for stability analysis are obtained. The following analyzes are performed within the stability calculation:analysis of the retaining wall stability to overturning, analysis of the retaining wall stability to sliding, analysis of soil stress at the contact surface, bearing capacity of soil. The calculation was done manually, as well as using the GEO 5 software system (Gabion Program).
