1引言
公路路基施工是整个公路施工工程的关键所在，稍有偏差，将给整个工程埋下质量隐患。例如，在公路施工中常会遇到诸如软土路基，黄土路基等不良路基，如不加以特别处理，会引起填方路堤施工后沉降或不均匀沉陷，路面纵横坡变碎，平整度下降，导致行车颠簸等，严重影响公路的正常使用，造成大量的人力、物力、财力浪费。因此，路基施工应根据施工当地地形、地质状况、公路等级、所在地区的气候、结合施工填挖方平衡等来选择施工方法。
2路基填压
公路路基的强度和稳定性很大程度取决于路基填料的性质及其压实的程度。从现有条件出发，改进填土要求和压实条件是保证路基质量经济有效的方法。
2.1路基填料
现行《公路路基设计规范》（以下简称规范）规定了对路基填料的要求。对路基填料的最小强度和最大粒径给了量化的标准，采用承载比实验（CBR）值表征路基土的强度，引入了路床的概念。对上路床的填料提出了限制条件，高速公路和

Roadbed construction is the key to the highway construction project, the slightest error will lay the whole project quality risks. For example, the Central Standing Committee met in the highway construction such as soft soil roadbed, roadbed and other bad loess roadbed, if not special treatment, would lead to construction of the embankment fill or uneven settlement after settlement, the road becomes broken vertical and horizontal slope, roughness decreased, resulting in road bumps, etc., seriously affect the normal use of the highway, causing a lot of manpower, material and financial resources to waste. Therefore, construction of embankment construction should be based on local topography, geology, road grade, where the region's climate, combined with the construction of such fill and cut Fang Pingheng to select the construction method.
