Abstract: A clamping triaxial seepage and acoustic coupling rock tensile testing machine includes a sample and a scaffold-type tensile testing device. The scaffold-type tensile testing device has an upper chuck and a lower chuck. The upper chuck has an acoustic transmitting channel, one end of which communicating with the outside, and the other end of which having an acoustic transmitting probe. The lower chuck has an acoustic receiving channel, one end of which communicating with the outside, and the other end having acoustic receiving probe. An upper end face of the sample has with a seepage outflow hole while the upper chuck has a seepage outflow channel connected with the seepage outflow hole. A lower end face of the sample has a seepage inflow hole while the lower chuck has a seepage entry channel is connected with the seepage inflow hole.

Abstract: A rock damage mechanics test system for high temperature and high pressure deep earth environment includes an MTS triaxial test machine and a control system connected therewith. The MTS triaxial test machine is composed of a rigid frame, a high temperature and high pressure triaxial chamber, and a triaxial chamber base. The control system includes a workstation for data processing and a manual controller for controlling the workstation and a master controller. The system improves mounting and dismounting efficiency of an MTS triaxial force sensor, enhances reliability of lifting and solves the problem of aligning holes during the force sensor mounting process, thus improving the mounting efficiency.
