摘要
简要介绍了铁路泥石流预报警报体系的构成和功能。在归纳分析资料采集内容和途径的基础上,总结并完善了评估泥石流沟严重程度的判识模型、泥石流暴发可能性的预报模型和铁路建筑物是否成灾的警报模型,并用实测资料对其进行了验证。
The safety of mountainous railways is often threatened by debris flows. How to effectively prevent the debris flow disasters and reduce the losses is the aim to study the forecast and forewarn system of railway debris flows in this paper. The factors to influence debris flow falls into the environmental factors and meteoric factors of a basin, and the judgment model of debris flow gully′s seriousness and the forecast model of debris flow occurrence are established. On the basis of analyzing the disaster-reducing effect of harness projects and anti-disaster probability of flood discharge projects, the forewarn model of debris flow disasters is built. These models form a complete forecast and forewarn system of railway debris flows. The models are verified by the data from a railway model section in good coincidence. The forecast and forewarn system will give a useful reference to the railway debris flow monitoring network to be built soon.
