摘要:
芒东盆地为拟建芒猴铁路必经之地，该盆地构造发育，地层岩性破碎且风化层厚度大，有利的地形和充足的降雨极易诱发泥石流灾害，给铁路选线带来极大的困难。本文借助现场详细勘察和遥感影像对芒东泥石流灾害特征进行了研究，在综合分析影响线路方案的泥石流灾害和其它地质问题的基础上，最终选择设桥通过泥石流堆积区。根据泥石流流量和淤积高度确定了桥梁的高度，并采取拦排结合的工程措施降低了泥石流对铁路工程的影响。研究成果可为类似工程的铁路选线提供参考。
Abstract:
The proposed Mangshi-Houqiao Railway will inevitably pass through the Mangdong Basin，which has developed structure，crushed rock mass and thick weathered layers. Favorable terrain and sufficient rainfall are easy to induce debris flow disasters，which brings great difficulties to railway route selection. For the purpose of this paper，the characteristics of debris flow along the Mangshi-Houqiao Railway were studied through detailed field investigation and remote sensing image. On the basis of comprehensive analysis of debris flow disasters and other geological conditions affecting the route selection，it was concluded to build a bridge to pass through the debris flow accumulation area. The height of the bridge was determined according to the debris flow rate and siltation height，and blocking and discharging were combined to reduce the impact of debris flow on railway engineering. The study results can provide a reference for similar projects.
