The issues, which affect the successful application of ground improvement in soil and rock, are studied rWqA)j*!
with emphasis on the design, construction and long-term performance of the improved ground. Discussed BIyG[y?qO
are over thirty technical issues affecting twenty four ground improvement techniques representing the eight !{lb#
main categories of ground improvement in soil: densification, consolidation, weight reduction, >C3 9`1
reinforcement, chemical treatment, thermal stabilization, electrotreatment and biotechnical stabilization. The 0pOha(,~
issues, which influence rock integrity, are also discussed, including those related to rock properties as well as H4Ek,m|c
external factors such as water, climate, earthquakes and others. Eight types of rock degradation are *?fBmq[j
described in the paper and possible remediation measures are identified for each, many of which include the 9V\`{(R
application of ground improvement. Several factors, which may influence the selection of a ground Sn&%epi
improvement technique or a combination of techniques, are discussed and a case study is presented to `BD`pa7.%
demonstrate the selection process.
