Vertical Load Tests of Footings on Silt

Abstract

Vertical load tests were performed on two shallow spread footings founded on nonplastic silt. Maximum vertical loads of 500 kips were applied to the test footings which were about 24 x 12 x 4 ft in size. Instrumentation was installed to measure footing displacements, footing contact stresses, and soil displacements below the footings. Results of the load tests have been presented in graphic form. Comparisons have been made between measured settlements of the footings and predicted settlements based on standard penetration test results in the silt deposit
