A test program was conducted to determine the effects of air surcharge on the bearing capacity of soft, cohesive soils. The test soils were of two types, fat clay and silt. The penetration resistance of a 3-sq-in. circular plate was selected as the measure of bearing capacity to be used. Cone penetration tests were performed also for control purposes. The plate penetration tests were conducted using air-surcharge pressures of 0, 1, and 5 psi. Test results show that the bearing capacity of the highly saturated, cohesive soils used in this study was not altered in any significant way by the application of air-surcharge pressures as high as 5 psi. As a corollary, it was found that cone index was linearly related to plate bearing pressure in each soil type, regardless of the air surcharge applied. Author
