Abstract:
The reuse of excavated fine-grained soils in earth structures like dikes under hydraulic conditions offers significant environmental and economic benefits. However, it raises questions regarding long-term durability when chemical stabilization is applied. In this study, the effects of curing duration and dosage on the soil’s microstructure, as well as its mechanical and hydraulic properties were investigated first on compacted soils with varying binder contents. A specific dosage was then selected for further study, and its characteristics served as a baseline to evaluate the effects of wetting and drying cycles. Finally, a physical model of a dike was designed and constructed to investigate how water level variations affect the treated soil properties.
Short bio:
Mohamed Ali is trained as a civil engineer. He first worked as a structural engineer for some time in Tunisia, focusing on buildings and various civil engineering works. His interest in geotechnics led him to enroll in the MSROE Master’s program, from which he graduated in 2023. He is currently enrolled in a PhD program under the supervision of Prof. Yujun Cui, in collaboration with TRACTEBEL and the SPTF, to study the long-term behavior of treated soils applied to the stabilization of dikes.
