摘要
与一般的土体不同,膨胀土具有吸水膨胀、失水收缩的特殊工程特性。简要介绍了膨胀土的成分与结构、物理化学性质、膨胀与收缩特性和膨胀土路基病害,并对膨胀土对公路路基的沉降变形与沉降量进行分析。
Expansive soil is different from the soil mass;it has special engineering characteristics of water swelling and drying shrinkage.Briefly introducing composition and structure,physicochemical property,dilatation and shrinkage character and subgrade disease of expansive soil,and analyzing the influence of expansive soil on the settlement and subsidence of highway.
