Cost-effective soil improvement and seepage control techniques in congested urban areas

Ground improvement is a common and essential engineering practice performed to improve the engineering properties of soils and ensure a certain level of safety to slopes and structures subjected to earthquake loading. When challenges such as limited surface access or the obligation to avoid soil disturbance are encountered, permeation grouting presents a cost-effective solution, if implemented appropriately. Currently, grouts are designed by practitioners based on experience and rules-of-thumb without properly accounting for key physical behaviors. Experimental studies have shown that grout propagation is affected by many factors that are not accounted for in current design practices. In this class, students will be given the necessary background related to grout flow and will perform hands-on experiments to assess the effect of gravity, mixing, filtration, and groundwater on grout propagation.
