... than that of the intact specimen. The in situ void ratio is ∼0.15 void ratio units less than the void ratio of the resedimented specimen at the in situ vertical effective stress; this suggests that creep deformation has occurred over geological time. In addition, the creep rate of the resedimented...

In this paper it was also reported and explained an unexpected influence of the creep deformation of the rock salt in the casing...

... to monitor the long-term shaft wall convergence. Monitoring of the extensometers occurred sporadically both prior to and after the installation of the lining over an approximately 2430 day duration. This data set provides important insight into the in-situ behavior of large scale creep deformations around...

... ABSTRACT: The main objective of this study is the description of both plastic and creep deformation of shale rocks by considering the influence of mineralogical compositions and porosity. To this end, a new micro-mechanics based approach is proposed. The microstructure of a typical shale rock...

For this purpose, we identify first and second order factors controlling the creep deformation of shales/mudstones. In turn, we compared the material...

... to the creep-induced closure of fractures. This paper reports a study on the influence of elevated temperature on the creep deformation of shale rocks. To this end, a series of multi-stage triaxial creep tests differing in stress conditions and temperature is carried out on two samples of the Mancos shale, one...
