Thermodynamic Properties of Soft Sedimentary Rock in Geotechnical Engineering
In geotechnical engineering such as supporting of deep and soft rock roadway, oil drilling, and construction of military underground defensive facility, thermodynamic properties of soft sedimentary rock has guiding significances. The study of the thermal constitutive behavior of rock under temperature has been done for many years, and many achievement have been got on this issue. In this paper, some experimental researches on the thermo-mechanical characteristics of soft sedimentary rock have been presented. Some test results have been simulated with a thermo-elasto-viscoplastic model. The results show that the proposed thermo-elasto-viscoplastic model reflects the visco-elastoplastic properties of rock, and can describe the thermo-mechanical behaviors of soft shale rocks in not only drained conventional triaxial compression tests but also drained triaxial creep tests. So it can be used for analysis of theology and stability of rock engineering.
