The utility model discloses a pressure chamber structure of rock mechanics triaxial compression test machine, include the pressure chamber that forms by base and last barrel be equipped with relative up -down's upward pressure head and overdraft head in the pressure chamber, the upward pressure head is connected with last dummy piston, go up dummy piston with go up the sealed sliding connection of barrel upward be equipped with pressure oil access way on the dummy piston go up dummy piston with be equipped with the sensor between the upward pressure head, the overdraft head is connected with lower dummy piston, down dummy piston with the base seals sliding connection. The utility model discloses can measure required tentation data automatically and accurately to the data stabilization is reliable, under the high confined pressure condition, dummy piston's external diameter is gone up in the accessible adjustment, makes the pressure chamber inside because the axial force that the confined pressure produced car
