摘　　要：DL/T 5144—2001《水工混凝土施工规范》第11.5.6条对混凝土质量验收标准作了较大变更。取消了我国水工混凝土质量验收沿用已久的标准。对此进行了研究讨论,建议恢复原有的验收标准,并采纳美国ACI 214标准小样本质量验收方法。对DL/T 5144—2001《水工混凝土施工规范》第11.5.6条提出了修改建议,供有关机构和人员参考。The Article 11.5.6 of Construction Specification of Hydraulic Concrete （DL/T 5144-2001） has made great revision on the acceptation standards of concrete quality and abolished the long-used standards of the acceptation of concrete quality in China. This paper studies and discusses this Article and suggests to resuming the original acceptation standards and to adopt the Small Specimen Quality Acceptation Method of American ACI 214 Standards. This paper puts forward the revision suggestions on the Article 11.5.6 of Construction Specification of Hydraulic Concrete DL/T 5144-2001, which Could be used for reference for relevant organizations and technicians.
