高山峡谷区农村公路水毁调查分析及防治

Investigation, Analysis and Prevention of Rural Highway Flood Damage in Alpine Canyon Areas

高山峡谷区,山大沟深、坡陡水流急,地质状况复杂、气候多变,水毁造成农村公路边坡亏坡、坍塌,混凝土路面面板悬空,安全防护设施损坏失效,部分桥涵受冲刷处于危险状态。文章通过现场实地调查研究,对高山峡谷区农村公路由降雨引起的公路水毁情况进行分类,并针对不同水毁类型,分析引起水毁的原因,并提出经济合理、可行的水毁治理和修复措施,尽可能消除安全隐患,确保高山峡谷区农村公路的畅通和村民的安全出行。

In alpine canyon areas, there are large mountains,deep ditches, steep slopes and rapid water flow. The geological conditions are complex and the climate is changeable. The flood damage causes the rural highway slope loss and collapse, the suspended concrete pavement panels, the damage and failure of safety protection facilities,and some bridges and culverts are in danger due to scouring.Through field investigation and research, this paper classifies the highway flood damage caused by rainfall in rural highways in alpine canyon areas, analyzes the causes of flood damage according its different types, and puts forward economic, reasonable and feasible flood damage treatment and repair measures to eliminate potential safety hazards as much as possible, so as to ensure the smooth flow of rural highways and the safe travel of villagers in alpine canyon areas.
