In order to solve these damages of subgrade settlement,pavement cracking and oversize post -construction settlement that the highways in collapsible loess area commonly appear, takeing the first - class highway of national highway 109 from Shiqigou to Qingshuihe for an example, the paper judges the collapsibility degree of loess according to collapsibility tests and proposes some treatment measures of collapsible loess foundation, which provide certain references for eliminating the hazard of col- lapsible loess foundation.
