金属波纹管涵洞是一种已经发展好多年,技术已经相当成熟的涵洞类型,它和混凝土涵洞在结构上有着本质的不同。金属波纹管在结构上具有横向补充位移的特性,又具有钢材抗拉性能强、变形能力优良的特点,对于应地基问题引起的基地应力不均匀而导致的涵洞应力集中的特殊要求,具有良好的适用性。 Metal corrugated pipe culvert is a type of culvert that has been developed for many years and has been quite mature in technology. It has essentially the same structural differences as concrete culverts. The metal corrugated pipe has the characteristics of lateral displacement compensation in the structure, and also has the characteristics of strong tensile strength and excellent deformation ability of the steel. The special requirements of the stress concentration of the culvert caused by the uneven stress of the foundation caused by the foundation problem have good applicability.
