The site of ancient Beiting city,an important town on the Silk Road,is located in Jimsar County and has significant historical,scientific,and artistic value.Because of natural conditions and human activities,the site is poorly preserved and shows severe deterioration in the form of fractures,rain erosion,wind erosion,and gullies urgently needing treatment.After investigating and analyzing the characteristics of the deterioration,this paper recommends the following conservation measures: building brick or stone supports or backfilling the areas of serious sapping erosion;using grouted anchors to consolidate the cracks that influence the stability of the earthen site;and grouting with PS material to consolidate the severely weathered surface.Having been optimized in field experiments,these conservation techniques have been applied in consolidation engineering projects,and have exhibited excellent conservation improvement.
