摘要
高强混凝土能有效降低桥梁结构自重并提高结构刚度,有利于增大桥跨、减少桥墩、增加桥下净空、降低平时维修费用以及延长使用寿命,因而在桥梁结构中具有巨大的应用潜力。
High-strength concrete can reduce its own weight and increase the stiffness of bridge structure, and is conducive to increase balk, to reduce the number of piers, to increase clearance under the bridge, and usually reduce maintenance costs and prolong service life. Given it has a huge application potential in bridge structure.
