Carolyn T. Conlee, Auteur ; Patricia M. Gallagher, Auteur ; Ross W. Boulanger, Auteur |This paper reports the results of two centrifuge tests that were conducted to evaluate the effectiveness of colloidal silica for liquefaction mitigation. Colloidal silica has been selected as a stabilizer material in soils because of its permane[...]

Daniel B. Chu, Auteur ; Stewart, Jonathan P., Auteur ; Ross W. Boulanger, Auteur |During the 1999 Chi-Chi Earthquake (Mw=7.6) , significant incidents of ground failure occurred in Wufeng, Taiwan, which experienced peak accelerations ∼0.7g . This paper describes the results of field investigations and analyses of a small regio[...]

Christopher L. Meehan, Auteur ; Ross W. Boulanger, Auteur ; J. Michael Duncan, Auteur |Movement along preexisting slickensided rupture surfaces in overconsolidated clay and clay shale slopes can represent a critical sliding mechanism during earthquakes. The seismic behavior of preexisting slickensided surfaces in overconsolidated [...]

Tadahiro Kishida, Auteur ; Timothy M. Wehling, Auteur ; Ross W. Boulanger, Auteur |The nonlinear dynamic properties of highly organic soils from two levee sites in the Sacramento-San Joaquin Delta in California are described. Cyclic triaxial, resonant column and torsional shear tests were performed on thin-walled tube samples [...]

Ross W. Boulanger, Auteur ; Daniel W. Wilson, Auteur ; I.M. Idriss, Auteur |A standard penetration test (SPT)-based liquefaction case history database for liquefaction triggering criteria is reexamined and reevaluated. The updated database incorporates a number of additional case histories, replaces prior estimates of e[...]

Richard J. Armstrong, Auteur ; Ross W. Boulanger, Auteur ; M. H. Beaty, Auteur |Earthquake-induced deformation of piled bridge abutments in approach embankments underlain by liquefied soils may be reduced by the restraining forces provided by the piles and bridge superstructure. Design methods accounting for these pinning e[...]

Erik J. Malvick, Auteur ; Kutter, Bruce L., Auteur ; Ross W. Boulanger, Auteur |This paper presents analyses of a test conducted on a 9-m-radius centrifuge to study the redistribution of pore water during diffusion of earthquake-induced excess pore pressures in a sand slope with embedded silt layers. The centrifuge model de[...]

Tadahiro Kishida, Auteur ; Ross W. Boulanger, Auteur ; Abrahamson, Norman A., Auteur |Regression models are presented for the dynamic properties of highly organic soils. The models are based on a database of triaxial and resonant-column/torsional-shear cyclic loading tests on thin walled tube samples mainly retrieved from the Sac[...]
