Abstract

A rock true triaxial dynamic compression-shear test equipment, and method under deep complex structure conditions, includes a counterforce framework, a pressure chamber, a base platform and four actuators. A pressure chamber transfer track is arranged on the base platform, and a pressure chamber transfer slipway is arranged on the tracks. The pressure chamber is a split structure. A pressure chamber base is located on the pressure chamber transfer slipway, and a pressure chamber barrel is provided with a pressure chamber barrel lift type bearing table and a pressure chamber barrel hoisting mechanism. The pressure chamber is provided with pressure chamber barrel and base packaging fixtures.
