A decomposition is used to express the mean squared deviation, quantifying dissimilarities between time histories of input (or response) quantities multiple replicas a soil system centrifuge test, as unique aggregate three discrepancy measures associated with shape, phase and frequency-shift. The shape measure quantifies deviations in form amplitude. estimates differences angle. frequency-shift frequency components. These are illustrated using simple synthetic motions assess discrepancies...
The mean squared deviation between acceleration time histories (of soil-system test replicas) is expressed as a unique aggregate of three discrepancy measures associated with shape, phase, and frequency-shift. shape-measure quantifies the deviations dissimilarities in form amplitude. phase-measure estimates differences phase angle. frequency-shift-measure frequency components. These were used to assess discrepancies among six replicas centrifuge experiment liquefiable soil tested at...
Observation and Measurement of displacements at the crown tunnel is an integral part New Austrian Tunneling Method (NATM) in complex rock masses to verify construction parameters, support systems safety requirements. However, prediction ground conditions ahead advancing face also application, often less explored field by site engineers. Literature suggests displacement vector orientation a good indicator weak or fault/shear zones face. There has been no quantification between properties...
The experimental results of two centrifuge test replicas a sloping (saturated-soil) deposit are used to assess the predictions (open source) software OpenSees. discrepancy between recorded and computed acceleration time histories is expressed as unique aggregate three measures associated with shape, phase frequency-shift. This decomposition sheds light on level consistency soil accelerations likely source inaccuracies in model prediction.
