Would anybody know anything about lime piling, i'm trying to look for information but not succeeding. If anyone has any suggestions on where to find information or if you yourself have any information, i would be most appriciative if you could help me out. Thanks. Brian.
I guess that by lime piles you mean soil stabilization using unslaked or slaked lime, introduce in the ground in prebored holes?
Yes, this method has been used in different parts of the world for instance to improve settlement characteristics of fine-grained soils below railway embankments. Holeyman and Mitchell have studies this topic: Title: Assessment of quicklime pile behaviour Author: Holeyman, A, Mitchell, JK Publication: Improvement of ground. European conference on soil mechanics and foundation engineering, 8, Helsinki, May 1983. Proceedings, Vol. 2 Publ data: s 897-902 Class code: K06, E13 Keywords: Soil stabilization, Pile, Lime, Model, Analysis, Conference, Helsinki, 1983, English
Several papers have been published on lime migration into surrounding soils: Title: Role of lime migration in lime pile stabilization of slopes Author: Rogers, CDF, Glendinning, S Publication: Quarterly Journal of Engineering Geology Publ data: 1996, vol 29, no 4, pp 273-284 Class code: D10, D02 Keywords: Clay, Soil stabilization, Lime, Migration, Chemical properties, Pile, Slope, English Abstract: /Reviews the literature on lime migration from piles and reports the results of recent research at Loughborough University to determine migration mechanisms from compacted quicklime piles. Potential applications are then discussed in the light of the findings/
A similar method has been used in the Far East (I think in India and Indonesia). Here is one reference:
Title: Lime pile treatment of black cotton soils Author: Rao, SM, Venkataswamy, B Publication: Ground Improvement Publ data: 2002, vol 6, no 2, pp 85-93 Class code: D10, K06 Keywords: Black cotton soil, Soil stabilization, Pile, Lime, Laboratory test, Swelling, Shrinkage, Control, English
Howeve, the method has not been economical and has been replaced by dry mixed-in-place columns. On this subject, many papers have been published.
