城际轨道交通无砟轨道大跨度连续刚构桥后期徐变控制措施研究
Research on Later Creep Control Measures of Large-span Continuous Rigid Frame Bridge on Intercity Rail Transit Ballastless Track
摘要
Abstract
In view of Guangzhou-Zhuhai intercity rail transit project RongGui waterway main bridge (115 m+2×185 m+115 m) of large-span continuous rigid frame bridge, the key technologies related to ballastless track are analyzed. The mixing proportion, slump, erosion resistance and corrosion resistance of C60 high performance concrete are studied. The materials shipped from the construction site including cement, sand, stone, fly ash and mineral powder are used to fabricate test beams to find out later creep characteristics of prestressed concrete beams and the control method. On this basis, corresponding control measures applied to design and construction are put forward.关键词
