摘　　要：山区地形复杂,桥墩高度变化多样,为桥墩选型带来了一定的困难。文章以甘肃省一处跨越深沟的组合箱梁桥为探讨对象,分析比较了在桥宽较窄时,不同墩高桥墩的稳定性、承载力和工程量,提出了不同类型桥墩适用的墩高范围。The mountainous terrain was complex, and the height of bridge pier varied,which brought some difficulties to the bridge pier selection. Based on a composite box grider across the deep ditch in Gansu province, this paper studied and compared the stability, bearing capacity and engineering quantity of bridge pier with different height when the bridge width was narrow. It put forward the height applicability of different types of bridge pier.
