Abstract

The invention relates to a test device for chemical solution seepage in rock single fracture at different temperatures. The test device comprises a sample apparatus system, an axial compression system, a confining pressure system, a chemical solution pressure loading system, a servo control system and a data acquisition system. The sample apparatus system comprises a sample, a cylindrical heat-shrinkable tube and a cylindrical rigid spacer block; one end of the rigid spacer block is provided with a permeation hole, a circular permeation groove and a radial permeation groove; the chemical solution pressure loading system is provided with a heating device; the heating device comprises a heater and a temperature sensor; the heater is disposed on a solution pipe at one side of the sample apparatus system; and the solution pipe between the heater and the sample apparatus system is provided with the temperature sensor. To increase test precision, the wall of the solution pipe between the heater and the sample apparatus system is provided with a heat insulation material; and a ceramic heater is employed.

Description

technical field [0001] The invention relates to a chemical solution seepage test device at different temperatures in a rock single crack, which is suitable for studying the chemical corrosion-stress coupling effect that occurs when chemical solutions at different temperatures seep through a rock single crack. Background technique [0002] Rock mass fissures usually dominate the migration direction of groundwater and are the main research object of seepage field. At the same time, due to the surface reaction mechanism controlled by mineral dissolution, the free contact surface of water-rock chemistry formed by joints and fissures is also the main place for geochemical reactions. Therefore, the existence of cracks in the rock mass greatly affects the balance of the mechanical field of the underground rock mass, the migration of groundwater in the seepage field and the progress of geochemical reactions. In view of the diversity of the occurrence environments of fracture surfac...
