当您看到新建郑州黄河公路大桥雄姿,或乘车飞弛在大桥之上的时候,您可曾想到支撑整个桥面的是959根预应力钢筋混凝土主梁吗?您可知道,正是由于主梁的设计、施工采用了预应力新技术,才使其具有足够的强度、刚度、韧性,从而满足了大桥对于车辆、人群、强风的承载能力和对于7(烈)度地震的抵抗能力。这项预应力技术,是由中国建筑科学研究院建
When you see the majestic of the newly built Zhengzhou Yellow River Highway Bridge, or when you ride on the bridge, do you think of the 959 prestressed reinforced concrete girders supporting the entire bridge? You know, it is because The design and construction of the main beam adopts new prestressing techniques to make it have sufficient strength, stiffness and toughness, so as to satisfy the bridge’s carrying capacity for vehicles, crowds, strong winds and resistance to earthquakes of 7 (strong) magnitude. This prestressed technology was built by China Academy of Building Research
