根据作者关于墨西拿海峡桥的建议,通过选用合适的建筑材料,例如用镀锌钢丝制作主缆和吊索,采用铝质加劲梁和轻质混凝土桥塔,即可大大降低大跨度悬索桥的造价,亦可充分满足发包人对空气动力稳定、承载能力、主梁挠度和抗震的要求。 According to the author’s advice on the Strait of Messina, the use of suitable building materials, such as main cables and slings made of galvanized steel wire, and the use of aluminum stiffeners and lightweight concrete pylons, can significantly reduce the Cost, but also fully meet the contractor on the aerodynamic stability, bearing capacity, girder deflection and seismic requirements.
