ABSTRACT:
Method of determining the pore water pressure in a soil, which includes installing a water-filled tube bearing a pore pressure sound at its lower end and said pore pressure sound bearing a filter through which the pore pressure in the soil is conveyed; lowering a measuring device down the tube and connecting it to the pore pressure sound; taking a reading which represents the pore pressure in the soil; disconnecting said measuring device from the pore water sound and then taking a reading which represents the water pressure in the tube; and calculating the pore pressure by comparison of the readings for the pore water pressure and the water pressure in the tube. A device for determining the pore water pressure is also provided.
