GROUND IMPROVEMENT ENGINEERING-ISSUES AND SELECTION

The issues, which affect the successful application of ground improvement in soil and rock, are studied with emphasis on the design, construction and long-term performance of the improved ground. Discussed are over thirty technical issues affecting twenty four ground improvement techniques representing the eight main categories of ground improvement in soil: densification, consolidation, weight reduction, reinforcement, chemical treatment, thermal stabilization, electrotreatment and biotechnical stabilization. Theissues, which influence rock integrity, are also discussed, including those related to rock properties as well as external factors such as water, climate, earthquakes and others. Eight types of rock degradation are
described in the paper and possible remediation measures are identified for each, many of which include the application of ground improvement. Several factors, which may influence the selection of a ground improvement technique or a combination of techniques, are discussed and a case study is presented to demonstrate the selection process.
