The invention discloses a rock
creep triaxial test
system and method capable of continuously acting in a
water environment, and belongs to the technical field of
rock mechanics tests. According to thetechnical scheme, a pressurizing cylinder is connected with a cross beam, the cross beam is supported on a testing
machine base through a supporting column, a
water environment confining
pressure system is arranged between the base and the cross beam, a
dynamic stress-strain collecting
system is connected with the
water environment confining
pressure system, and the
dynamic stress-strain collecting
system is sequentially connected with a computer, a digital controller, a
servo controller, a hydraulic source and an oil conveying
pipe. The rock
creep triaxial test system and method have the beneficial effects that the
hydration reaction of an expanding agent is used for replacing a constant-flow pump to provide confining pressure for a triaxial test, the cost is reduced, and the rock creeptriaxial test system and method are continuous and stable; the long-term
mechanical property of the rock can be tested under the continuous action of chemical solutions with different components; thelong-term mechanical properties of the rock in static and flowing water environments can be tested, the pH value change of the water environment caused by
corrosion of water to the rock can be monitored in real time, and the hydrochemical reaction characteristics of the rock are obtained; and moreover, the mixed expanding agent is good in expanding effect.
