合肥至六安高速公路膨胀土路用性能试验研究

结合野外调查和室内试验两种方式，对合肥至六安高速公路膨胀土的分布、物质组成及物理力学性质进行详细研究，发现膨胀土在水平向及垂直向存在一定的差异性。在利用各项综合指标对膨胀土进行等级划分的基础上。分别对胀缩性及压实性进行试验研究，最终得出的结论对于路基施工设计具有一定的指导意义。

Swelling Soil Roadbed Function Test of Highway From Hefei to Liu'an

The distribution, physical component and mechanical property of swelling soils of highway from Hefei to Liuan were detailed studied using field investigation and laboratory testing, and conclusions were arrived at that there were some differences between the properties on horizontal orientation and that on vertical orientation. By grading the swelling soils according to compositive indexes, swelling and shrinking properties and press density were selected as two indexes for studing, and the final results will supply some learning for pavement construction design.
