SLOPE STABILISATION USING REINFORCED LIME PILES

Practical details are given of the use of lime piles on the construction of the London Underground Jubilee Line. The problems experienced with poorly constructed embankments are examined and the maintenance difficulties caused by the problems are discussed. The paper describes how lime piles provide a cost effective solution to stability problems and how they are currently being applied to further sections of the line. The manner in which slope stability is improved by the introduction of lime is explained. It creates a demand for water present in the clay, introduces a material whose strength gains as it absorbs water and modifies the clays around the pile to increase their shear strength. Mechanisms investigated include suction, shear strength of the pile and the clay. For the covering abstract see IRRD 887532.
