About this Research Topic
Hydro-mechanical (HM) coupling and creep behaviour in geomaterials are significant due to their important role in assessing the long-term stability of geological engineering , such as oil and gas extraction, nuclear waste disposal, dam, and mine engineering, etc. This behaviour is also relevant for Earthquake Engineering and Environmental engineering. Laboratory tests have confirmed that HM coupling, although affected by various petrophysical quantities, has shown to be strongly dependent on the geometry of fracture networks, fluid characteristics and stress conditions. Creep deformation mechanisms have been a subject of great interest and considerable debate and controversy. Although some creep models have been derived, based on theoretical studies and laboratory creep tests. These equations are still uncertain because they are not confirmed by in situ data. Therefore further studies on HM coupling and creep behaviours of geomaterials, such as permeability, creep characteristics and nonlinear flow laws in complex geomaterials are still needed.
This Research Topic will include papers on different topics related to hydro-mechanical coupling and creep behaviours of geomaterials, such as experimental founding and constitutive models and their engineering applications. In particular, the latest research achievements related with nonlinear fluid flow laws and new creep models in complex geomaterials subjected to 3D stresses will be encouraged.
The aim of this Research Topic is to cover recent research trends in hydro-mechanical coupling and creep behaviours of geomaterials. A broad range of submissions in theories, experimental techniques, numerical methods and engineering projects is welcome. Areas to be covered in this Research Topic may include, but are not limited to:
• Nonlinear flow behaviours in geomaterials;
• Creep characteristics of geomaterials;
• Mechanical and permeability characteristics of geomaterials;
• Constitutive modelling and numerical methods;
• Case studies related to hydro-mechanical coupling of geomaterials; and
• Case studies related to creep of geomaterials.
