Abstract:The calculation of drainage and seepage in the basement of Jiudian Plaza in Foshan was introduced in detail. Using PLAXIS 2D software and GTS NX 3D software, combined with different parameters of geotechnical and hydrogeological prospecting, different permeability coefficient combinations and stratification differences of main rock and soil layers were considered to calculate seepage in pits and corresponding surface subsidence, and various possible influencing factors on seepage were discussed. The calculation shows that the design of drainage can be adopted in this project.

Keywords:releasing water buoyancy; seepage quantity calculation; settlement calculation
