A cohesive soil sample is subjected to an unconfined compression test. The sample fails at a pressure of 3850 lb/ft2 [i.e., unconfined compressive strength lb/ft2]. Determine the soil’s cohesion.
A flexible steel platform has a footprint of 75 feet by 75 feet and supports equipment having a total weight of 2,250 kips. The platform is located at the ground surface. The soil profile below the platform consists of 30 feet of stiff clay over bedrock. The groundwater table is located 5 feet below the ground surface. The clay has a unit weight of 120 pcf above the water table and 125 pcf below the water table. Laboratory consolidation test results for a sample of the clay at a depth of 15 feet below the ground surface reveal a preconsolidation stress of 2,400 psf, compression index of 0.5, recompression index of 0.1 and initial void ratio of 0.66. Assume the bedrock is incompressible. Part A Plot effective vertical stress versus depth (to scale) before and after installation of steel platform and equipment. Part B Calculate the primary consolidation settlement at the center of the platform and at the corner of the platform AND report the differential settlement between these two…
