“…By using the back-analyzed method and embedding the numbers in Figure 11, it could be seen that the liquefaction samples A1 to A3, which are in the shaded zone, located on Olson & Stark (2002) [7] upper bounds. Baziar and Dobry (1995) [44] and Olson and Stark (2002) [7] proposed the relationships between liquefied shear strength and prefailure vertical effective stress as shown Figure 12. Of course, Baziar and Dobry (1995) [44] further analyzed the case histories used by Seed and Harder (1990) [36] and Stark and Mesri (1992) [37] and developed these boundaries.…”

An experimental study is carried out to investigate the static liquefaction of sand. For this purpose, Babolsar sand with its liquefiable parameters such as soil properties and high seismic level of underground water are investigated using static compression drained and un-drained tri-axial tests under isotropically and anisotropically conditions. Also, the data results of this sand are compared with those of the previous studies on soil case history. The study results indicate that Babolsar sand can experience the whole possible states of liquefaction soil, i.e. flow failure, limited and dilation behavior.

“…Figure 4A presents curves that show the probability of liquefaction occurrence (P L ) between 5 and 95 percent. referred to as steady-state shear strength (Poulos, 1981;Poulos and others, 1985) and residual strength (Seed, 1987;Seed and Harder, 1990;Baziar and Dobry, 1995). Slopes that have undergone disintegrative flow failure experience large strains such that the soil mass flows (Whitman, 1985).…”

“…At a given subbottom depth, the downslope gravitational driving shear stress is a function of the sediment buoyant density and sea-floor slope angle. The resistive residual strength of the delta sediment was estimated by the relation proposed by Baziar and Dobry (1995) for silty sand. Using the soil boring logs of the delta front, we computed residual strengths from the SPT dataset for units of clean sand and silty sand deposits using a mean profile through the zone of likely residual strengths reported by Baziar and Dobry (1995).…”

Barnhardt 2 AbstractA highly developed commercial-industrial corridor, extending from the City of Kent to the Elliott Bay/Harbor Island marine terminal facilities, is founded on the young Holocene deposits of the Duwamish River valley. The deposits of this Holocene delta have been shaped not only by relative sea-level rise but also by episodic volcanism and seismicity. Ground-penetrating radar (GPR), cores, in situ testing, and outcrops are being used to examine the delta stratigraphy and to infer how these deposits will respond to future volcanic eruptions and earthquakes in the region. A geotechnical investigation of these river-mouth deposits indicates high initial liquefaction susceptibility during earthquakes, and possibly the potential for unlimited-strain disintegrative flow failure of the delta front.
