Transportation Infrastructure on Soft Sensitive Clays: Some Essential Aspects and Examples

Soft sensitive clays in Norway may be a major threat to nearby transport infrastructures due to their tendency to remold when being loaded to failure. Soft sensitive clays deposits may cause catastrophic events, due to the possibility of small landslides initiating a fast and extensive retrogression process, which may involve massive soil movements on the order of millions of cubic meters. In this paper, the effort is made to demonstrate these using some simple examples and analytical solutions. The paper shows that the very fundamental properties like undrained shear strength (Cu), shear strain (γ ) at the intact (Cui) and the remolded state (Cur), soil sensitivity (St) and the stiffness parameters of soft sensitive clays are closely interrelated. Therefore, the mechanical behavior of soft sensitive clays requires an integrated study of these parameters because results only based on individual parameters could be misleading. This is elaborated using the concept of remolding energy.
