摘要: Ground improvement will be critically important in future geotechnical practice to achieve reductions quantities of material used, reduction carbon footprint, prevention and mitigation natural disasters, treatment recycling industrial wastes, remediation polluted soils, development brownfield sites maintenance rehabilitation existing structures. Challenges exist providing cost-effective sustainable ground under current economic conditions. These issues are addressed categories reduce, reuse recycle the first part paper. Selection processes for methodologies, improved analysis, knowledge long-term performance understanding effects variability required develop more efficient designs. second
