title = "Geo-treatments in constructing a tunnel in karst strata: Lessons learned from a subway project in Guangzhou, China",
abstract = "This paper presents tunnel construction in caved karst strata base on the metro subway project between Maanshan Park station and Liantangnan station (Ma-Lian section) of Guangzhou metro line No. 9. The karst is highly developed with 98 karst caves along the tunnel route. The soil in the tunnel zone mainly consists of soft residual deposit, sand and slightly weathered limestone, which are unstable during construction. Complicated ground conditions were encountered during tunnel excavation, such as upper-soft-lower-hard ground, sand layer and caved karst. Geological risks including sink holes, water or stone ingress, and damage to constructed tunnels and the shield may occur during tunneling in the project of Ma-Lian section. Construction problems may be encountered during tunneling excavation, such as caved karst treatment and tunneling in complicated ground. Recommended solutions and modifications are proposed to solve the above problems.",
