Abstract
Earth retaining structures usually need careful monitoring after construction in order to detect any signs of distress. In cases where failure is likely to occur, appropriate remedial techniques need to adopted, backed by a detailed analysis. This paper presents a case study on the rehabilitation of a retaining wall that was constructed for a bypass road project. The structure showed clear signs of distress immediately after completion and hence could not be opened for traffic. Preliminary finite element analysis of the wall showed values of factor of safety that are lesser than permissible values. The values of factor of safety obtained from limit equilibrium analyses based on overturning, sliding and bearing pressure were also inadequate. Soil nailing with grouted nails has been suggested as a remedial measure for this case. The results of the finite element analysis of the wall reinforced with grouted nails are presented in this paper. Results show that the soil nailing technique is effective in the rehabilitation of the wall.

Case Study on the Rehabilitation of a Distressed Retaining Wall

Earth retaining structures usually need careful monitoring after construction in order to detect any signs of distress. In cases where failure is likely to occur, appropriate remedial techniques need to adopted, backed by a detailed analysis. This paper presents a case study on the rehabilitation of a retaining wall that was constructed for a bypass road project. The structure showed clear signs of distress immediately after completion and hence could not be opened for traffic. Preliminary finite element analysis of the wall showed values of factor of safety that are lesser than permissible values. The values of factor of safety obtained from limit equilibrium analyses based on overturning, sliding and bearing pressure were also inadequate. Soil nailing with grouted nails has been suggested as a remedial measure for this case. The results of the finite element analysis of the wall reinforced with grouted nails are presented in this paper. Results show that the soil nailing technique is effective in the rehabilitation of the wall.
