... of intact rocks. The above-mentioned geological deformation could in turn affect tunnel structural deformation. Moreover, the long-term strength degradation of rock mass due to chemical weathering could exacerbate this influence. Thus, it is essential to develop a modelling framework that can capture...

... core plugs were selected to conduct rock mechanical tests before and after salt precipitation. Ultimately, a mathematical model was established to investigate the mechanism of rock strength degradation. The results of sand production prediction indicated that sand production from rock skeletons should...

... to a progressive strength degradation and consequently a severe closure (i.e., squeezing) of the roadway. In this study, numerical simulation was carried out to investigate the mechanisms of roadway squeezing using UDEC Trigon approach. The strength degradation is simulated by gradually reducing the cohesion...

... time-dependent strength degradation, seismicity, gas generation, and glacial loading/unloading cycles. This paper describes a series of analyses performed to explore rock mass stability and geological barrier integrity. Reservoir Characterization Upstream Oil & Gas strength reservoir...

... ABSTRACT Rock strength degradation in the context of sand production refers to a process where the initially intact rock gradually breaks down into completely disaggregated and producible aggregates in response to hydrocarbon production. A close examination of routine laboratory geomechanical...

... ABSTRACT ABSTRACT This paper presents a Bureau of Mines study on the time-dependent behavior of coal measure rocks. The change in weight of Illinois shales due to moisture adsorption was examined. The relationships between moisture adsorption and strength degradation under isothermal...
