Abstract:
The durability and stability of sea dikes have become a sustained concern with continuous sea level rising due to climate change. In this study, the mechanical behaviour of a lime-treated silty soil for sea dike construction in hydraulic and saline environments was investigated, with emphasis on the microstructure evolution. The laboratory experiments, combined with the field monitoring data from an experimental sea dike, provided insights into the deterioration mechanisms. Based on the experimental results, a constitutive model was developed, accounting for the coupled effects of salinity and lime content.
