The issues, which affect the successful application of ground improvement in soil and rock, are studied m<7Ax>
with emphasis on the design, construction and long-term performance of the improved ground. Discussed ]! @z3Hv3
are over thirty technical issues affecting twenty four ground improvement techniques representing the eight criQa<N"
main categories of ground improvement in soil: densification, consolidation, weight reduction, W 9i}w&
reinforcement, chemical treatment, thermal stabilization, electrotreatment and biotechnical stabilization. The L#t^:%
issues, which influence rock integrity, are also discussed, including those related to rock properties as well as 8>U{>]WG
external factors such as water, climate, earthquakes and others. Eight types of rock degradation are <ttrd%VW
described in the paper and possible remediation measures are identified for each, many of which include the vpt *?eR
application of ground improvement. Several factors, which may influence the selection of a ground R,]J~TfPK
improvement technique or a combination of techniques, are discussed and a case study is presented to 9T`$ gAI
