The issues, which affect the successful application of ground improvement in soil and rock, are studied / e~
with emphasis on the design, construction and long-term performance of the improved ground. Discussed H @3$1h&YS
are over thirty technical issues affecting twenty four ground improvement techniques representing the eight ,gAr|x7_
main categories of ground improvement in soil: densification, consolidation, weight reduction, )a4E&D
reinforcement, chemical treatment, thermal stabilization, electrotreatment and biotechnical stabilization. The +~R.7NE%
issues, which influence rock integrity, are also discussed, including those related to rock properties as well as |_Naun=+~
external factors such as water, climate, earthquakes and others. Eight types of rock degradation are +=n
x|:no
described in the paper and possible remediation measures are identified for each, many of which include the r?Ev.m
application of ground improvement. Several factors, which may influence the selection of a ground !nP8ysB
improvement technique or a combination of techniques, are discussed and a case study is presented to asm[-IB2u
demonstrate the selection process.
