摘要
An apparatus and method for determining time-dependence failure under constant temperature through high pressure true triaxial loading for hard rock, includes a pressure chamber and four actuators, wherein a sample bearing platform is arranged in a center of the pressure chamber, a sample bearing and containing chamber is arranged in a center of the sample bearing platform, and a confining pressure loading oil supply hole is formed in the sample bearing platform, and communicates with a confining pressure loading injection pump; each actuator includes a sealing cover, an annular end cover, a counter-force cylinder barrel, a piston, a piston rod, a sealing flange and a stress loading injection pump; a heating coil is arranged in the pressure chamber; a force sensor is fixedly mounted at the end part of the piston rod; and a pressure sensor is mounted in the sample bearing platform.
