Dams and Levees

Assignments usually include static and seismic slope stability evaluations, seepage investigations, and seismic retrofit evaluations. In particular, this experience focuses on the static and seismic shear behavior of fine-grained/cohesive soils, evaluating liquefaction potential of sandy soils, the behavior and magnitude of the post-liquefaction shear strength of soils for seismic remedial measures of dams and levees, and 2-D and 3-D slope stability analyses using Spencer’s (1965) stability method for dams.
