In this text, the basic method and theory of quality control of construction engineering are studied by combining the project instance. Firstly, the origin of quality control, domestic and international situation of the development at quality control is briefly introduced. 本文在研究建设工程质量控制基本方法和理论的基础上,结合工程实例对质量控制问题进行了探讨。
The yield point, quality grade and deoxidation are used to express the brands of steels, which reflects the features of engineering structural steels. The new standards are also favorable for technical exchange internationally for China's products to enter international market. 钢的牌号表示方法改为用屈服点、质量等级、脱氧程度表示,反映了工程结构钢的特点,便于使用选材.新标准与国际接轨,便于与国际进行技术交流和我国产品进入国际市场。
