Foundation Treatment Methods of Metro Station on Geological Sensitive Area
The vital geological risk factors including in saturated soft clay stratum, water-rich fracture zone, Karst stratum with abundant soil caves and saturated sand stratum on the safety of metro station are discussed. The successful experiences of controlling the geological risks in metro projects are summarized. The design methods of metro station foundation and main structure at geological sensitive areas are presented. It is concluded that hazards of foundation settlement, pit collapsing, and water gushing are more easily taking place in metro stations with saturated soft clay stratum. Failure of soil and water inrush often happened owing to the water-rich fracture zone. Collapse and subsidence frequently come up at the area of Karst stratum with abundant soil caves. The water bursting and sand flowing is usually broken out at the foundation pit with saturated sand stratum. The safety of metro station with the above-mentioned defective geological factors can be controlled and ensured through targeted design schemes and construction methods.
