摘要
膨胀土作为一种典型的非饱和土,具有显著的吸水膨胀软化和失水收缩开裂特性,它在全世界范围分布较广,对水利、道路等工程建设的危害较大,由于防治困难,膨胀土的工程问题一直以来都受到国内外学术界和工程界的高度重视。
Expansive soil as a typical nonstaturated soil has the outstanding saturate and expanding softening and cracking feature when loses water.It is widely used in the world which poses huge risks for water conservancy and road.Since it is difficult to prevent,the engineering problems of expansive soil has always been paied much attention from domestic and foreign people in this field.
