混凝土是水运工程中基本建筑材料之一,其质量的优劣直接影响着建筑物结构的使用年限。应用数理统计法控制混凝土质量,是评价混凝土制作水平、建立科学管理制度,确保混凝土工程质量的有效措施之一。目前,我国一些规范(《钢筋混凝土结构设计规范》TJ10-74和《港口工程混凝土和钢筋混凝土规范》设计与施工部分)均已引入强度保证率概念,并规定运用数理统计
Concrete is one of the basic building materials in water transport projects. The quality of concrete directly affects the service life of the structure of the building. The application of mathematical statistics to control the quality of concrete is one of the effective measures to evaluate the level of concrete production, establish a scientific management system and ensure the quality of concrete engineering. At present, some norms in our country (“Design Code for Design of Reinforced Concrete Structures” TJ10-74 and “Port Engineering Concrete and Reinforced Concrete Code” part of the design and construction) have introduced the concept of strength assurance rate, and provides for the use of mathematical statistics
