Infiltrating properties of modified swelling soil subgrade;

Through the site test-road monitoring,indoors modeling test and other technical methods,it proposed a computing theory for the design of the swelling soil subgrade,improved the design methods for the reinforced swelling soil subgrade and developed an economical and proper treatment method for the swelling .

Water-destroyed disaster of expansive soil roadbed and it s forecast based on rough neural network;

Forecast mode of water-destroyed disaster for expansive soil roadbed

Connecting with the practice of Xi an-Nanjing railway engineering,and starting from various diseases of the expansive soil roadbed,and according to the engineering features of the expansive soil and the reasons of the diseases,this paper puts forward some measures and methods for preventing these.

Study on determination of treatment depth for expansive soil subgrade in Hefei;

In allusion to the subgrade damage form of expansive soil, the cause of damage is analyzed and the solving measures of expansive soil subgrade are expounded combining with one case, which can provide reference for treating this kind of subgrade.

It introduces the scheme design and construction technology of the swelling soil foundation treatment with lime-soil compaction pile in the special railway line K15+000～K15+100 in Chengzhuang of Jincheng coal group in detail,and analyzes the quality check contents and application effect,which will supply reference to the similar projects.
