Abstract

The paper sets out the salient features concerning the failure of a retaining wall on a sloping ground. The retaining wall experienced a displacement of about l.50 m both in the downward and outward directions without experiencing any tilt or structural distress. The stability analysis of the slope on which the retaining wall was located, established that the failure was caused by inadequate drainage of the fill resulting in a build up of pore pressures. Four more such retaining wall sections were also analysed. The remedial measures consist of providing adequate drainage using a geotextile - covered filter drain, use of light weight saw dust back fill to reduce the disturbing moments, in the case of the retaining wall that experienced movement. In the other sections, suitable regrading of the slope in front of the retaining walls along with a slight reduction in the height of the backfill was found to be the most economical solution available.

Restoration of the Stability of Retaining Wall

The paper sets out the salient features concerning the failure of a retaining wall on a sloping ground. The retaining wall experienced a displacement of about l.50 m both in the downward and outward directions without experiencing any tilt or structural distress. The stability analysis of the slope on which the retaining wall was located, established that the failure was caused by inadequate drainage of the fill resulting in a build up of pore pressures. Four more such retaining wall sections were also analysed. The remedial measures consist of providing adequate drainage using a geotextile - covered filter drain, use of light weight saw dust back fill to reduce the disturbing moments, in the case of the retaining wall that experienced movement. In the other sections, suitable regrading of the slope in front of the retaining walls along with a slight reduction in the height of the backfill was found to be the most economical solution available.
