摘要
从岩土的水理性质出发,采用现场调查和理论分析相结合的方法,研究季节性冰冻区公路路基边坡中水的侵蚀机理问题和公路路基边坡溜方的稳定性影响,得出公路路基边坡坡面径流流速的关系公式和季节性冰冻地区公路路基边坡的滑动面平行于路基边坡坡面的结论,通过季节性冰冻地区公路路基边坡的应用实践举例,提出季节冰冻地区公路路基边坡水害的治理措施。
This paper using the method of site investigation and theory analysis,in terms of geotechnical waterphysical property,researches the mechanism of theory of water erosion on highway subgrade slope in seasonal frost area and the slope slide effection,with conclusion of radial flow velocity flow relation formula and subgrade slope slip plane paralleling to grade surface,and puts forward the measures for highway subgrade slope slide prevention in seasonal frost area the treatment of highway subgrade slope flood damage.
