【正文】 According to the highway subgrade slope protection [abstract] this article through the analysis of road foundation slope failure forms and reasons, analyzes the roadbed slope protection design principles, detailed introduces the highway slope protection method, in order to guarantee the stability of roadbed and prevention and control of all kinds of roadbed disease, to ensure the normal use of the highway quality and benefit of investment [key words] highway subgrade slope protection Roadbed protection is to guarantee the stability of roadbed strength and one of the important measures, protection is the focus of the embankment slope, the change of the terrain, ShiLu design elevation and natural ground conductivity of the relationship between different, there will be higher than that of the natural ground embankment fill subgrade construction of the ground below natural excavated one that cut and between the two and a half between fill subgrade in geotechnical engineering by half to dig into roadbed fill dug, change the original layer of the natural balance, and exposed to a natural environment, longterm affected by various natural factors, the physical and mechanical properties of rock mass will been great changes, cause rock mass deformation mobile, destroy the stability of the slope, and even cause a series of geological environment problems and the ecological environment problems, such as collapse landslides of soil erosion and damage to vegetation, etc .So to ensure the stability of roadbed and prevention and control of all kinds of roadbed disease, in addition to the drainage roadbed, still need to be bined with the local hydrological geology and material of case, take effective measures to all kinds of soil ShiBianPo necessary protection. Firstly,a slope failure forms and reasons Embankment slope of the slump is one of the most mon roadbed disease, according to slope soil category damage reason and scale is different, the main failure form of slip party peel and broken down landslide collapse four slip party is due to a small soil slope moves down along the soil formed, namely the slope of thin surface soil slip under, it is often due to rainfall precipitation and flowing water erosion caused by improper slope or construction of the landslide is refers to the part of the gravity of soil slope under one of the sliding surface sliding, mainly because of the soil slope of embankment caused by inadequate stability of landslide is the main reason of the side slope s
