Abstract The swelling of clay-sulfate rocks is a well-known phenomenon often causing threats to the success various geotechnical projects, including tunneling, road and bridge construction, geothermal drilling. origin usually explained by physical due clay expansion combined with chemical associated transformation anhydrite (CaSO 4 ) into gypsum ∙2H 2 O). latter occurs through dissolution subsequent precipitation. Numerical models that simulate rock must consider hydraulic, mechanical,...
Abstract We developed a coupled hydro-mechanical (HM) model based on semi-logarithmic swelling law to reproduce the outcomes of tests clay-sulfate rock specimen collected from Freudenstein tunnel, which was constructed in Triassic Grabfeld Formation (formerly Gipskeuper = “Gypsum Keuper”) Southwest Germany period 1987–1991. The were conducted using an oedometer apparatus under constrained (no strain) or constant load conditions. used strain–time data obtained laboratory testing calibrate HM...
Calcium sulfate exists in three forms, namely dihydrate or gypsum (CaSO4·2H2O), anhydrite (CaSO4), and hemihydrate bassanite (CaSO4·0.5H2O) depending on temperature, pressure, pH, formation conditions. The of calcium sulfates occurs widely nature many engineering settings. Herein, a dataset containing the experimental solubility data minerals, i.e., anhydrite, aqueous solutions is presented. compiled contains values extracted from 42 papers published between 1906 2019. can be used for...
Underground in situ pyrolysis and gasification is an important method to enable clean utilization of lignite China. In this study, using the high-temperature triaxial permeability test equipment for different ranges temperature pore pressure, mechanical characteristics from Pingzhuang Mine Area Chifeng have been examined. The results show that, at constant confining elastic modulus decreases with increasing temperature. For up approximately 75°C, close under uniaxial state. As increases,...
