Abstract:
The basic principle for the consolidation of the wetsubsidence loess subgrade is to destroy the macroconfiguration of the wetsubsidence loess so as to eliminate the wetsubsidence feature. Some portions of TongYan highway are located in wetsubsidence loess zones. In order to guarantee the safety and normal performance of the subgrade and structures of the highway, impaction and compaction method is adopted to consolidate the subgrade consisting of nongravity wetsubsidence loess before backfilling so that the subgrade can meet the requirements in respect of bearing capacity and stability.
Key words: nongravity wet subsidence loess  , ground consolidation  , impaction and compaction method
