摘要: 针对以往山区公路沿河路基失稳破坏的研究限于地表水对路基的冲刷作用而并没有揭示出沿河路基内在失 稳机理这一局限性,从水在岩土体中的渗流这一角度出发,概述沿河路基岩土体内的孔隙压力及渗透压力发生变化 而使岩土体发生变形破坏及地下水对岩土体的各种不良作用。

关键词: 山区公路, 路基, 渗流, 失稳机理

Abstract: The former researches about unstable failure of roadbed Mong rivers in the mountainous area are limited in the surface. water erosion,and don't reveal the immanent instability mechanism of roadbed along rivers.From the point of water seepage in rock-soil mass,the deform ation and damage of rock-soil mass because of the changes of pore-pressure and osmotic-pressure were summaried,and kinds of harmful efects because of the underwater were concluded.

Key words: mountainous highway, roadbe d, seepage, mechanism of instability
