In this state-of-the-art report, a comprehensive review of the latest developments in geotechnical construction methods and some emerging techniques is presented. The review focuses mainly on four topics: (1) ground improvement, (2) deep excavation and tunnelling, (3) natural hazard mitigation and (4) dredging and land reclamation. Other topics such as grouting and groundwater control are also discussed briefly. Different construction methods for each topic are summarised or classified. The principles and mechanisms of different construction methods are outlined. Applications of some of the most recent construction methods are illustrated using case histories. Many references on the topics discussed are also referred to in the report.
