Expansive Soil Subgrade Design for Expressway from Dengzhou to He'nan and Hubei

文章结合某高速公路膨胀土路基设计,对影响路基、边坡稳定性的因素进行分析,通过采用换填路基材料,控制边坡,制定防护、排水措施,保证膨胀土地区道路在较长时间内路基的稳定和路面的平整度,达到安全舒适行车的目的。

Combining with expansive soil subgrade design of an expressway, the affecting factors on the stability of roadbed and slope are analyzed. By using the replacement of subgrade material,controlling slope,developping protective and drainage measures, the stability of the road in the expansive land area and the smoothness of the pavement in a long time are ensured, the safe and comfortable driving purpose are achieved.
