Abstract

The hydrostatic pressure calculation method, which cannot consider the block effect of the underground structure on seepage, is used to calculate the buoyancy of the underground structures in practice nowadays. This will lead to inaccurate calculation of buoyancy. A series of finite element analysis are conducted to investigate the water level distribution around the structure under the condition of the seepage. The influence factors and the distribution rules of the underground water level around the structures are revealed based on the results from FEM. Then an empirical method is proposed to calculate the underground water level around the structure considering the block effect of the underground structure on the seepage. Through validation, the proposed method is proved to be reasonable to calculate the underground water level for calculation of buoyancy on structures considering the block effect of structures on seepage.
