成兰铁路泥石流防治措施

Prevention and Control Measures for Debris Flow on Chengdu-Lanzhou Railway

山区铁路泥石流爆发频繁,对铁路影响较大,应采用合理防治措施,降低或减少危害。本文利用成兰铁路泥石流试验专题和科研成果,对泥石流进行防治。通过理论计算和分析,详细论述了泥石流对铁路的影响程度和危害,提出了跨越泥石流沟的桥梁采取相应的工程措施,并通过工程实践验证了防治措施的合理性。研究结论可为类似铁路泥石流防治提供借鉴。

Debris flow breaks out frequently on railways in mountainous areas,having a great impact on the railway.Reasonable prevention measures should be taken to reduce or mitigate harm.This paper introduced the debris flow study for Chengdu-Lanzhou Railway with its study results,and proposed the method to prevent and control debris flow.Through theoretical calculation and analysis,the impact degree and harm of debris flow on railways were discussed in detail,corresponding engineering measures were proposed for bridges crossing debris flow ditches,and the rationality of prevention and control measures was verified through engineering practice.The conclusions can provide a reference for the prevention and control of debris flow in similar railways.
