The issues, which affect the successful application of ground improvement in soil and rock, are studied {Lb NKjn
with emphasis on the design, construction and long-term performance of the improved ground. Discussed (tP>z+
are over thirty technical issues affecting twenty four ground improvement techniques representing the eight MFaK=1
main categories of ground improvement in soil: densification, consolidation, weight reduction, ^6mlE+WY
reinforcement, chemical treatment, thermal stabilization, electrotreatment and biotechnical stabilization. The zht^gOs
issues, which influence rock integrity, are also discussed, including those related to rock properties as well as <g5Btwo%
external factors such as water, climate, earthquakes and others. Eight types of rock degradation are |[}YM%e
described in the paper and possible remediation measures are identified for each, many of which include the `#A&v
application of ground improvement. Several factors, which may influence the selection of a ground 41mg:xW(J
improvement technique or a combination of techniques, are discussed and a case study is presented to $[}31=0
demonstrate the selection process.
