An Instrument to Measure Skin Friction and Normal Earth Pressure on Deep Foundations


An apparatus which simultaneously measures skin friction and normal earth pressures while deep foundations such as piles and cassions are being driven has been developed. The instrument has three major parts: casing, pressure cell, and cantilever. The casing protects the pressure cell which measures lateral earth pressure. Strain gages on the cantilever, which screws into the back of the casing, measure skin friction. The instrument has been tested by embedding it in a precast concrete pile driven in natural soil. The comparison between the measured and computed values indicates the the promising nature of the instrument.
