Calculation of reinforced soil retaining wall to ensure the stability of the slope
The article analyzes the state of the object located on the slope. To ensure the stability of the slope, it was decided to build a reinforced ground retaining wall with a height of 6 m. For the reinforcement was used woven geotextile with a tensile strength of Tu = 50 kN / m. The parameters of the reinforcement of the retaining wall were determined by an analytical method. The length of the reinforcing elements was taken to be different along the wall height from 1500 mm to 4000 mm. Reinforcement spacing 200 mm. Then, calculations of the slope with the reinforced ground retaining wall were performed using the finite element method using the Plaxis 2D program. according to the calculated models of plane strain. In the calculation used permanent and temporary loads from the building. The calculation was carried out in 7 phases: activation of the reinforcing layers with a length of 1.5 m, replacing the soil with the backfill soil; activation of reinforcing layers with a length of 2.0 m with the replacement of soil on the backfill soil; activation of reinforcing layers 2.5 m long with the replacement of soil on the backfill soil; activation of reinforcing layers with a length of 3.0 m with the replacement of soil on the backfill soil; activation of reinforcing layers with a length of 3.5 m with the replacement of soil on the backfill soil; activation of reinforcing layers with a length of 4.0 m with replacement of the soil on the backfill soil; load activation from the projected building. As a result of the calculation, the maximum displacement of 28 mm was obtained.
