Field Investigation on Wall Facing Deformation of Mechanically Stabilized Earth (MSE) Walls Constructed using Cement Modified Marginal Soil with Built-In Facing

Abstract: It appears that the reasonable way of providing a realistic approach for Mechanically Stabilized Earth (MSE) walls is to construct model walls in the field and study their performance at failure. Hence, it was decided to study the behaviour of model MSE walls constructed using conventional (standard) backfill and marginal soils. This study was undertaken to investigate the mechanism, qualitative behaviour and potential benefits of using cement modified marginal backfill soils under cyclic loading. A field study was undertaken to evaluate the performance of model non–woven geotextile reinforced MSE walls constructed using locally available marginal backfill soils without and with cement modification. In the present study, an attempt was made to make a built–in soil cement facing out of same backfill soil with extended reinforcement into it, which is folded back within the lift thickness. As this type of built–in facing that does not involve the connection problems and tried as an alternative to conventional facing panels. The facing deformations were measured using dial gauges during load testing. The load testing was continued until failure of the respective walls was reached.
