| Abstract: | Against the bad properties of high liquid limited soil of Guangzhou-Wuzhou Highway,a series of indoor experiments is carried out to test the soil sample’s physical mechanics indexes;depending on the cluster analysis theory,the soil samples are classified and the various feature values and improvement programme are confirmed;then the testing items of soil improvement are defined according to the correlation distance of the soil sample and the feature values.Taking the determining course of improvement programme of new soil material as the example,the application of research conclusion is introduced. |
