摘要:
The design and construction of infrastructures such as tunnels, dams and embankments, on soft clay deposits is an engineering challenge because of the very complex behaviour of natural clays. Various fundamental aspects of the behaviour of natural soils, such as anisotropy, change of structure at the microscale and viscosity influence the soil response to loading. Whilst, accurate long-term predictions require models that take into account the viscosity of soft soils. The presentation will be made of two parts: (1) the development of elasto-viscoplastic models for natural clays accounting for anisotropy, viscosity, destructuration and their coupling effects will be illustrated; (2) the application of the models to some geotechnical structures such as a tunnel in soft clays and embankment on soft clays will be showcased.
