摘要
水毁路基是山区公路水毁的主要类型之一。本文以四川境内公路水殴路基的发育为例,从成因关系上对山区公路水毁路基的发育机制进行了研究。研究表明,河流冲刷切割型、推挤错位变动型、重力剪切破坏型和机械撞击破坏型水毁路基是山区公路常见的4种路基水毁类型。这一成因分类研究为有效地防治山区公路水毁路基、减少重复水毁奠定了理论基础,具有很强的理论意义和实际意义。
Base-wasting of highways,one of the typical wastings of highway in mountain area,is quitewidespread in Sichuan area, On the basis of the researches about base-wasting of highways in Sichuanarea,this paper canvasses the basically developmental mechanism of wasting.The wasting can be divid-ed into four types,,i.e. Scouring-downcut,deforming-push,shear rupture and hitting rupture,TheclasSification has important interests in the theory and application for the prevention and cure of wast-ing in mountain area.
