WebVarious mechanical properties of stabilised peat, like undrained shear strength, unconfined compressive strength and shear strength was determined after 14 days of curing time. Scanning electron micrograph (SEM) and energy dispersive x-ray (EDX) test were also conducted to observe the microstructure of stabilised peat soil. ... WebIn case of evaluating stability of soft ground using circular slip analysis, it is very important to determine the undrained shear strength (S u) of the ground. Meanwhile, fibrous and high organic peat is distributed widely in Hokkaido, the northernmost island of Japan.
Deformation and Shear Strength Characteristics of Some …
WebThe soil stiffness was calculated with two different formulas based on the soil type. For cohesive soils, K h = 60 ·c u /d, where K h is the subgrade reaction, and c u is the undrained shear strength of the soil; for cohesionless soils, K h = n h ·z/d, where n h is the coefficient of the subgrade reaction, z is the soil depth, and d is the ... WebJul 21, 2024 · The direct shear test experiment was carried out to investigate the possibilities of estimating the undrained strength of peat using the direct shear test (DST). The first set of direct shear test was performed in the laboratory on 38 reconstituted peat samples using variable displacement rates estimated from \(t_{f}\) of 0.065 \(t_{50}\) to … thomas bagel thins
