摘要
随著科学技术的发展,桥梁逐渐朝向大跨距、减轻自重、轻质、耐久方向发展的今天,应用轻质粒料混凝土不但可减少构材断面、增大结构跨度、提高空间使用效率,对桥梁设计及施工竞争力也会有所提升。
With the development of science and technology, bridges gradual y toward the direction of large span, reduce weight, lightweight, and durable to develop today and the ap-plication of lightweight aggregate concrete not only can reduce the structural material section, increase the span structure and improve the efficiency of space service, but also improve the bridge design and construction competitiveness.
