Abstract:As per technical specifications in New Doha Port Project, the ground shall be improved to medium dense to dense for granular deposits and firm to stiff for cohesive deposits. CPT is proposed as ground testing method after ground improvement. Firstly, soil classification is undertaken based on cone resistance and friction ratio of CPT. Thus soil is classified into granular and cohesive type. For granular deposits, CPT acceptance criteria are established by the correlation between relative density and cone resistance. For cohesive deposits, CPT acceptance criteria is established by the correlation between undrained strength and cone resistance. The soil classification system and two types of acceptance criteria based on CPT are greatly suitable for ground testing and they are worth popularizing.
