中文摘要：
针对我国第一条穿过青海察尔汗盐湖的国道215线察尔汗盐湖—格尔木高速公路工程的桥梁结构混凝土的耐久性设计要求,开发了适用于盐湖地区桥梁工程的高性能混凝土技术,并成功地应用于实际工程。近3年的实际工程考验表明,所配制的C50低渗透性高性能混凝土具有高强、抗氯离子扩散渗透、抗冻、抗盐湖卤水腐蚀和抗裂等特征,满足我国西北高海拔盐湖地区的混凝土结构工程的使用要求。
英文摘要：
Aimed at our country the first through Qinghai Chaerhan Saline Lake road 215 line durability design requirements of concrete bridge structure of Chaerhan Saline Lake-Golmud highway engineering,high performance concrete technology is developed for the bridge engineering in the Saline Lake,and successfully applied in actual engineering. The practical engineering test showed that nearly 3years,the prepared C50 high performance and low permeability concrete has high strength,resistance to chloride ion diffusion penetration,frost resistance,corrosion resistance of Saline Lake brine crack resistance and other characteristics,meet the use requirements of structural engineering concrete in high altitude area of Saline Lake in Northwest China.
