When the seepage of water is upward in a soil layer so much that seepage force decreases the inter particle forces and effective stress is reduced to zero, quick sand condition occurs. Liquefaction of sand is also a phenomenon when effective stress of soil is reduced to zero, it usually occurs when sand deposit is shaken due to an earthquake or any other oscillatory load which increases the pore water pressure.

Flow Condition in Soil with Zero Effective Pressure
When the effective pressure of soil is reduced to zero, certain flow conditions may occur. The two main flow conditions that occur in this situation are:
1. Quicksand Condition:
This flow condition occurs when the effective pressure of soil is reduced to zero and the soil particles are no longer in contact with each other. As a result, the soil behaves like a fluid, and the weight of the overlying soil causes the soil particles to become buoyant. This can lead to the formation of quicksand, where the soil appears solid but can quickly collapse or liquefy when disturbed.
2. Liquefaction Condition:
This flow condition occurs when the effective pressure of soil is reduced to zero and the soil loses its strength and stiffness. The soil particles become rearranged and the soil behaves like a liquid. This condition can occur during earthquakes or other dynamic loading events, where the vibrations cause the effective stress to decrease and the soil to liquefy. This can lead to soil settlement, foundation failure, and other types of damage.
In summary, when the effective pressure of soil is reduced to zero, flow conditions such as quicksand and liquefaction can occur, which can have serious implications for the stability and safety of structures built on or in the soil. It is important for civil engineers to take these conditions into account when designing foundations and other structures that rely on the support of soil.
