摘要
与一般路基相比,高填方路基具有填方高度大、较高耐久性和稳定性等特点,具有施工成本低、使用寿命长等优点.为保证道路的稳定和可持续发展,在我国山区公路经过地势低洼地区路段时,往往采用高填方路堤形式.然而,高填方路堤会出现严重的沉降,从而导致路基不稳定,特别是在黄土地区.通过具体工程实例,对黄土地区高填方路堤沉降进行现场监测,对其沉降影响因素及控制技术进行总结分析,为黄土地区高填方路堤建设提供更好的指导.
Abstract
Compared with the general subgrade,the high-filled subgrade has the characteristics of large filling height,high durability,high stability,low construction cost,long service life and so on.In order to ensure the stability and sustainable development of road,the high-filled embankment is often adopted when the mountain highway passes through the low-lying areas in China.However,there will be serious settlement of the high-filled embankment,which leads to the subgrade instability,especially in loess area.Through the practical engineering cases the in-situ monitoring is carried out for the settlement of high-filled embankment in loess area and the influencing factors and control technology of its settlement are summarized and analyzed,which provide the better guidance for the construction of high-filled embankment in loess area.
