... of surrounding rock of deep underground cavern, the triaxial creep tests of deep hard rock under different temperatures were carried out based on an important hydropower station. According to the tests results, under the high temperature and long-term load, the granite has the following creep characteristics: (1...

... their strength in different confining conditions. Finally, triaxial creep tests were performed to estimate the strength variation with orientation. Results from X-ray Diffraction (XRD), uniaxial and triaxial tested specimen showed the brittle behavior of shale. Specimens cored parallel to the bedding plane...

... ABSTRACT: The creep behaviour of a soft rock can be examined by experimental studies involving triaxial creep tests and tunnel physical model tests. The physical model tests show a close resemblance to the developed numerical analysis using fitted creep parameters determined by triaxial creep...
