Research conclusions: For construction of the connecting passage inwater- enriched sand bed, the artificial ground freezingmethod is a prior construction method featuredw ith high reliability and no pollution ofgroundwaterand ground. oreover, in order to ensure the successful and safe application of the artificial ground freezingmethod, theduct piece at the tunnelportal of the connecting passage should be designed specially. In order to reduce the mi pact of expansive soil on the tunnel
