Abstract: 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 ...

Abstract: 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 ...

Abstract: The dynamic properties of peat have been identified as major source of uncertainty in the evaluation of seismic hazards throughout the Sacramento–San Joaquin Delta in northern California. This paper summarizes the results ...

Abstract: The nonlinear dynamic properties of a fibrous peaty organic soil beneath a levee in the Sacramento–San Joaquin Delta in California are described herein. Thin-walled tube samples were obtained from four locations between ...
