Study on Design of Salt Rock Subgrade in Dry Salt Lake Area along Lop Nur to Ruoqiang Railway
摘要
Abstract
Since the Lop Nur to Ruoqiang Railway passed through the Lop Nur'Big Ear'lacustrine plain area,this paper compared and analyzed the similarities and differences between the salt rock of the Lop Nur salt lake and the salt rock of the Chaerhan salt lake.According to the transportation distance and geological conditions of the soil field along the line,combined with the design of the soft soil foundation treatment drainage cushion and the medium-coarse sand barrier,the salt rock was reasonably used as the roadbed filler after the scheme comparison and selection,and the salt rock subgrade construction is proposed.The proposed method adopted the engineering measures of upper sealing and underwater isolation,and selected the new geotechnical synthetic material with better durability,which could effectively ensure the good stability of the salt rock filler.关键词
