Brian D. Collins, Auteur ; Sitar, Nicholas, Auteur |An investigation into the geotechnical properties specific to assessing the stability of weakly and moderately cemented sand cliffs is presented. A case study from eroding coastal cliffs located in central California provides both the data and i[...]

Brian D. Collins, Auteur ; Sitar, Nicholas, Auteur |The analysis of steep slope and cliff stability in variably cemented sands poses a significant practical challenge as routine analyses tend to underestimate the actually observed stability of existing slopes. The presented research evaluates how[...]

Gang Wang, Auteur ; Gyimah Kasali, Auteur ; Sitar, Nicholas, Auteur |A prototype pier load test program was performed to study the load-deformation and energy-dissipation characteristics of the response of drilled piers under static and dynamic axial loads. The field tests consisted of six fully instrumented dril[...]

Doolin, David M., Auteur ; Sitar, Nicholas, Auteur ; Ooi, J. Y., Éditeur scientifique |Discontinuous deformation analysis (DDA) is a discrete element method that was developed for computing large deformation in fractured rock masses. In this paper we present details of the DDA time integration scheme, where the acceleration is tak[...]
