摘要
龙泉山区的公路建设等级较低,公路水毁灾害分布面广,水毁灾害发生频繁且危害巨大,严重影响了当地的交通运输营运与安全,造成了重大经济损失.该文从实地调查入手,深入分析龙泉公路水毁的致灾原因,指出路基标高过低、洪水冲刷公路弯道、泥石流以及路段边坡病害等是引起公路水毁的主要原因,并针对水毁灾害提出相应的治理措施.
Road construction standard is relatively low in Longquan mountainous area where road flood damage is widespread and in high frequency with deadly consequences.This not only seriously affects the operation and safety of transportation,but also results in significant economic losses to the locals.This paper,starting from field surveys,provides in-depth analysis of the causes of flood damage in Longquan,e.g.flood erosion highway curve,low roadbed elevation,mudslides,road slope disease etc.Finally,control measures are proposed to prevent flood damages.
