摘要: 公路泥石流水毁灾害是我国山区公路建设与养护的重大地质灾害类型,具有出现频率高、分布范围广、灾情严重等基本特性。基于对国内外研究文献的检索和分析,山区公路泥石流水毁灾害研究现状可概化为4个方面,即公路水毁机制、泥石流动力学、公路水毁危险性评价和公路水毁防治技术,详细梳理了每方面的研究进展;基于山区公路泥石流水毁灾害减灾需求,指出了现有研究存在的薄弱环节,如泥石流磨蚀作用及泥石流沉积物固结机理、泥石流淤埋路段、沿河公路路基缺口部位公路交通应急通行技术、沿河公路路基及桥涵水毁力学机制;提出了进一步实施山区公路泥石流水毁灾害防灾减灾研究的4个方向,即泥石流复杂介质动力学特性、沿河公路路基及桥涵水毁机制、公路水毁路段应急通行技术、公路泥石流水毁灾害应急安全警报方法、系统与设备,详细解读了每个研究方向的主要思路。

Abstract: Debris flow and flood disaster is the major geological disaster in highway construction and maintenance in China, with high frequency, wide distribution, serious damage and other basic characteristics. Based on the search and analysis of domestic and foreign research literature, the research status of flood disaster of mountainous highway debris flow could be generalized into four aspects, including the highway washout of flood, debris flow dynamics mechanism, evaluation of flood hazard of highway and highway flood prevention technology, and the research progress of every aspect was elaborated. Based on the reduction demand of mountainous highway debris flow disaster, the weaknesses of the current research were pointed out, such as debris flow erosion and debris flow sediment consolidation mechanism, mud-rock flow-silting road section, highway traffic emergency access technology at the roadbed gap of highway along river, damage mechanics mechanism of highway roadbed and bridges along river. Four directions for further research on reduction of flood disaster and debris flow disaster in mountainous highway were proposed, namely is, the dynamic characteristics of debris flow in complex medium, highway roadbed along river and bridges damage mechanics mechanism, highway road emergency traffic technology, emergency safety warning method, system and equipment of road damaged by debris flow disaster. And the main thought of each research direction was interpreted in detail.

Key words: road engineering, research status, research trend, debris flow and flood disasters, mountainous highway
