In a laboratory compression test, the void ratio in a soil sample changes from 1.46 to 1.32 when the compressive loading increases from 100 kN/m2 to 200 kN/m2. Calculate the value for the coefficient of compressibility and the compression index for this load range.
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…
For an unconfined compressive strength test on a soil having USCS classification of CH and sample diameter of 2 inches, the axial load on the sample at failure (15% strain) was 300 pounds. What is the undrained shear strength, Su, of the sample in pounds square foot (with end area correction)? Sketch and label the Mohr's Circle and failure envelope.
A consolidated, undrained tri axial test was carried out on a 73.0 mm diameter and 146.6 mm-long decomposed granodiorite sample at an initial water content of 26%. The sample was obtained from Palmerston Highway, North Queensland, Australia, to back-analyze a slope failure, and wasinitially consolidated under a cell pressure of 200 kPa and backpressure of 150 kPa. The drainage valvewas dosed and the cell pressure was increased to 254 kPa when the pore water pressure increased to182 kPa. Find Skempton's B-parameter. The nature of the soil sample is such that it was not possibleto achieve a higher B value. The drainage valve was opened and the sample was consolidated furtherunder the cell pressure of 254 kPaand backpressure of 150 kPa. At the end of consolidation, the drainage valve was dosed, locking in thebackpressure in preparation for the undrained loading.

5. A laboratory consolidation test was performed on a cohesive soil specimen with drainage on top and at the bottom. The original height of the specimen was 2.54 cm. Based on the log time versus deformation data, the time to achieve 50% average degree of consolidation was 11 min. Calculate the coefficient of consolidation (in cm²/min) for the soil sample.
Assume that both a triaxial shear test and a direct shear test are to be performed on a sample of dry sand. When the triaxial shear test is performed, the specimen fails when the major and minor principal stresses are 80 and 20 lbs/in^2, respectively. When the direct shear test is performed, what shear strength can be expected if the normal stress is 4000 lbs/ft^2? Show all work.

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.

The foundations supporting two columns of a building are shown in Figure E9.16. An extensive soil investigation was not carried out, and it was assumed in the design of the foundations that the clay layer had a uniform thickness of 1.2 m. Two years after construction the building settled, with a differential settlement of 10 mm. Walls of the building began to crack. The doors have not jammed, but by measuring the out-of-vertical distance of the doors, it is estimated that they would become jammed if the differential settlement exceeded 24 mm. A subsequent soil investigation showed that the thickness of the clay layer was not uniform but varies, as shown in Figure E9.16. The owners would like to get an estimate of the expected total differential settlement and how long it will take before the doors become jammed. 780 kN| 780 kN Foundation A Foundation B 1.5 m x 1.5 m 1.5 m x 1.5 m Sand. 1.4 m 3 m 2.8 m 1.2 m Clay, m, = 0.7 m²/MN Gravel FIGURE E9.16
