You need to determine the strength parameters for soil retrieved during a shallow excavation. It was found that 28% of the soil had a particle size greater than 425 µm and only 8.5% of the soil had particle sizes less that 75 µm. Which method is probably the most accurate way to determine the strength parameters of the above soil if your intention is to install a retaining wall to keep the soil in place as deeper excavations are carried out? Select one: a. Sample in situ with Split Spoon Tube followed by the appropriate laboratory tests. b. Use SPT c. Use VST d. Sample in situ with Shelby Tube followed by appropriate laboratory test.

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.
Geotechnical Engineering Please help me answer this question, and please show your solutions write it properly. Problem 1 A soil sample has moist unit weight equal to 16.5 kN/m3), water content of 15%, and specific gravity of 2.70. Find the dry unit weight and the void ratio for this soll Problem 2 A soil sample has a total unit weight of 16.5 KN/m3 and a void ratio of 0.84 The specific gravity of solids is 2.70. Determine the degree of saturation and the moisture content of the soil.
A sand deposit has been identified beneath a site located adjacent to a river. The sand deposit is 30 feet thick and the top of the layer is 24 feet below the ground surface and overlain by a very stiff clay and is underlain by bedrock. The water level has been measured to be at a depth of 30 feet. The standard penetration resistance of the layer has been determined to be 20 blows per foot and a sampler without liners was used; a drill rig with a safety hammer with an efficiency of 60% was used. The length of the drill rod is 5 meters and the borehole diameter is 7.87 inches (200 mm). The design earthquake has been designated as a moment magnitude 7.5 event on a nearby fault and the maximum ground acceleration is expected to be 0.60 g. The wet unit weight of the clay soils is 200 pounds per cubic foot and the wet unit weight of the sand soils is 250 pounds per cubic foot. The sands have 45% fines content according to a grain size analysis. Determine the cyclic stress ratio, CSR.…
Compare the final settlement magnitude of the soil samples in the two scenarios explained below between time t1 and time t2. Note: The answer must include a short explanation of the reason too. 1) The soil sample is compacted and subjected to one-dimensional consolidation loading under 200 kPa. After completion of the consolidation stage, it is unloaded and consolidated to 10 kPa (time=ti). Afterwards, the axial stress on the soil is increased to 200 kPa (time=t2). 2) The soil sample is consolidated under 10 kPa (time=ti), 50 kPa, 100 kPa and finally 200 kPa (time=t2).
please help me... If a soil sample tested in a direct shear box of 60 mm by 60 mm and the maximum readings for normal loads of 0.3, 0.5 and 1.0kN were 202, 265 and 511 kN, determine the strength parameters corresponding to effective stress. Please find: 1) UU test; Unconsolidated Untrained (Q-test or quick test) 2) CD test; Consolidated Drained ( S-test or slow test) 3) CU test; Consolidated Untrained (R-test) 4) UC test; Unconfined Compression (σ_3=0) Thank you..
Q2. (a) You are given the following results from Atterberg Limits testing on a soil sample (PL= 23%, LL = 55%) collected from a boring on a local project site. The soil sample had natural moisture content of 56.3% prior to Atterberg Limits testing. If the soil is fine grained, what is the USCS Group Symbol (refer to Figure 2a) on page 7 for this soil and what does the natural moisture content result tell you about the soil in-situ (i.e. “in place")?
Please solve this problem and explain each step clearly, Please explain the theory and show your work clearly, I really want to understand. Thank you
A soil sample has the following size distribution; 4 to 2mm = 17%, 2 to 0.05 mm = 12%, 0.5 to 0.005 mm = 22% 0.005 to 0.002 mm = 10% <0.002 mm = 39% what is the percent clay silt and sand? What are the modifier and textural classification?
Not interested in the calculations, just want to see the graph so please display that for me instead of the e calculations. Note) For soil sample in Table 2, initial thickness of sample = 14.31 mm, sample area = 2827.433 mm^2 , dry weight measured at the end of test = 52.53 g, specific gravity = 2.7. (Please draw graph possible) Also Determine the compression index and expansion index using graph
During a laboratory consolidation test with double- drainage system, a 20 mm thick clay sample underwent 90% consolidation in 10 minutes. If another sample of the same soil is tested with single drainage with all other conditions remaining same, what would be the time required for it to undergo 90% consolidation?
