| 摘 要： | 在路基设计与施工中,对路基压实度的控制有时带有一定的盲目性,压实结果不是浪费就是不足。如果施工方案不到位,很容易形成各种病害,影响公路的使用效果。通过分析路基工作区深度与公路等级、路面类型、路基土回弹模量及荷载轴重的关系,提出了基于路基工作区深度和填挖关系的变化来确定分段压实度方案的方法,以指导施工。

| Abstract: | In foundation design and construction,subgrade compactness is sometimes controlled with blindness and compaction result is waste or insufficiency.If construction program is not proper,various diseases are possibly formed,influencing service effect of road.This paper analyzes the relation between subgrade working area depth and highway grade,pavement type,resilience modulus of subgrade soil,and load axle weight.It puts forward the method to determine sectional compactness program based on the relation between subgrade working area depth and cutting and filling height so as to guide construction. |

| Keywords: | highway subgrade subgrade working area subgrade cutting and filling height subgrade compaction |
