针对多哈新港项目中的地基验收标准（即经地基处理后，砂性土须达到中密-密实，黏性土须达到硬塑-坚硬），提出采用CPT作为地基检测方法。首先通过CPT的端阻、摩阻比确定地层土类，划分成砂性土及黏性土两大类，然后分别提出两类土的CPT验收曲线：对于砂性土，通过相对密度与CPT端阻的关系，推导得到砂性土达到中密-密实状态时对应的CPT验收标准；对于黏性土，通过不排水抗剪强度与CPT端阻的关系，推导得到黏性土达到硬塑-坚硬状态时对应的CPT验收标准。采用该地基验收方法简便快捷，值得在大面积的地基处理检测中推广应用。

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.
