Abstract:The engineering properties of the Hebeng high-speed rail are analyzed.Free expansion rate,grain composition test index is obtained through the indoortest of typical soil samples.Different lime-doped rates test of several typical soil sample were conducted.Reasonable lime-doped rates of Hebeng high-speed rail expansive soil is determined according to the strength and swell-shrink and rational water index.
