Impact of colloidal silica treatment on an earthfill dam

Autor: Fraccica, Alessandro, Spagnoli, Giovanni, Enrique Romero, Arroyo, Marcos

Publikováno v: Web of Science

The impact of the use of sand treated with Colloidal Silica (CS) on a model 80 m high-earthfill dam was assessed through numerical modelling. The hydro-mechanical properties of the CS-Treated soil were taken from a previous laboratory study. Differen
