摘　　要：以"涩宁兰输气管道巴音河穿越段水工保护工程"为实例,采用管道河流穿越工程中广泛应用的冲刷经验公式,对该穿越段的冲刷深度进行计算,通过对比分析各计算结果的合理性与可靠性,提出了符合实际情况的水工保护工程基础埋置深度,为油气输送管道穿越段水工保护工程设计与工程基础埋深的确定提供了技术参考和较可靠的科学依据.Taking Bayin River Crossing as an example,which is only a sechis of Hydraulic Protection Project for Sebei-Xining-Lanzhou Gas Transportation Pipeline,we have calculated the depth of scour in this section by using the scouring empirical formulae that have been widely used in the pipeline engineering.We have analyzed the reliability and appropriateness of the calculated results.On this basis,we put forward the depth of foundation to the hydraulic protection project according with the actual situation,thus pro...
