Affected by hydraulic potential gradient, the unsaturated soil water in the furrow soil may supply laterally the ridge soil of adjacent furrow.
The distribution law of pressure potential in saturated soil using two-ring infiltration method to determine the permeability coefficient was different to that using cutting ring method.
Square large-span structures are set in the saturated soil, and overall damage appears for these structures.
Natural sinkholes generally form when heavy, water-saturated soil causes the roof of an underground limestone cavity to collapse, or when water widens a natural fracture in limestone bedrock.
The results supported that the initial shear wave velocity of loose saturated soils was a key parameter controlling its cyclic liquefaction resistance.
