Buoyancy Force Acting on Underground Structures considering Seepage of Confined Water

Table 2

Summary of system calibration, homogeneous soil layer, and overlying aquiclude tests.

Test series	Test case	Description
System calibration	S0	The structure is placed in pure water.
Homogeneous sand	H1	The structure is embedded in fine sand, and the water head difference is 0.
	H2	The structure is embedded in fine sand, and the water head difference is 10 cm.
	H3	The structure is embedded in fine sand, and the water head difference is 20 cm.
Layered soil with confined water	O4	The structure is embedded in overlying aquiclude, and the water head difference is 0.
	O5	The structure is embedded in overlying aquiclude, and the water head difference is 10 cm.
	O6	The structure is embedded in overlying aquiclude, and the water head difference is 20 cm.
