On June 21, with the completion of the No. 2 Tunnel of Indonesia's Jakarta-Bandung High-Speed Railway, the construction of all 13 tunnels on the whole line was finished, laying the foundation for its scheduled launch in June 2023. These 13 new tunnels have a total length of 16,643 meters. The regions where the tunnels are located have the geological characteristics of clay, soft mud, sandstone and thin covering soil, which might easily lead to instability of tunnel structure, deformation or even landslides and indicate extremely difficult engineering and high risks. The No. 2 Tunnel in Purwakarta County, West Java Province, has a total length of 1,052 meters and a maximum buried depth of 53.6 meters, making it one of the most difficult projects throughout the railway.
