Very broad distribution of loess , in which the thickest loess Northwest Territories , the most complete and well developed , all strata , characterized by more typical . Because loess has a special collapsible loess area excavation frequent highway disease . Firstly, on the loess engineering characteristics and its influencing factors are analyzed , summarized , proposed loess of treatment measures , and then loess excavation area highway disease extensive survey results are analyzed disease causes and conditions, loess excavation area roadbed disease control measures were studied, specifically including reasonable slope section design , road bed treatment measures , protection and support engineering diseases and prevention measures and anti excavation subgrade drainage facilities and other parts. In this paper, a variety of loess foundation treatment method when a study that combines a variety of construction methods in various highways have been built on the Treatment of findings, analysis of its effect is presented in practical engineering Treatment reasonable and effective means for the future refer to the application project .
