Abstract

The invention discloses a rock porosity real-time tester under chemical seepage and creep coupling, belonging to the rock engineering technical field, which is composed of a rock sample clamp, a chemical seepage pressure loading device, an axle pressure loading device, a surrounding pressure loading device and a porosity tester. The rock porosity real-time tester can real-timely test the porosity of a rock sample under constant pressure loading and chemical seepage coupling of three directions, having simple structure, flexible assembly, strong expandability, high stability and wide application. The rock porosity real-time tester has high application value for rock soil mass mechanical property and seepage character research under multi-field coupling condition of rock-soil engineering, hydraulic engineering, petroleum engineering, mining engineering and underground engineering and the like.

Description

technical field [0001] The invention relates to a real-time testing device for rock porosity under the coupling action of chemical penetration and creep, which is mainly used for real-time testing of rock porosity under the coupling action of different three-dimensional constant stress levels, different types of chemical solutions, and different osmotic pressures device. It belongs to the field of rock engineering. Background technique [0002] The research on the change of physical and mechanical properties of rocks in the process of chemical infiltration and creep coupling is a frontier topic in the field of international rock mechanics. How to quantitatively describe the effects of chemical infiltration and creep coupling on the deformation and failure process of rocks from the perspective of experiments has become a rock. It is a key scientific problem that urgently needs to be solved in mechanics and major engineering, and porosity is one of the main parameters reflect...
