Abstract The Antuoshan and Qiaoxiang Stations of the Shenzhen Metro line 2, which pass through water-rich sandy stratum, demonstrate the successful implementation of the auxiliary measures of ground dewatering, advance grouting, and jet grouting. Additionally the measures of hanging protection were adopted during tunnel construction under gas lines with intermediate pressure, ensuring the construction safety of the drill and blast tunnel and the gas lines.
