The treatment of collapsible loess soils using cement materials

摘要

Loess is a metastable collapsible soil, whose collapse can cause significant distress to the built environment across the world. This paper presents a case history illustrating how with proper pre-treatment assessment and careful selection, a cement based treatment approach was used successfully to improve a collapsible loess soil. This case history illustrates that even for structures when very tight specifications for post treatment performance exist, it is still possible to build safely on a problematical loess soil.
