Static adjustment of CRTS I double-block ballastless tract in Wuguang high speed railway

Wuguang high speed railway is the first HSR in China which adopted CRTS I double track ballastless.By using this track bed,the exactly adjustment of track can be achieved when the jointless track laying and stress release of long rail is complete.The exactly adjustment of track can be divided into two stages.Based on engineering practice,the static adjustment techique of unballasted track was illustrated from construction preparation,datas collection and field adjustment.
