Abstract

The invention provides a rock mass fracture unsaturated seepage test system. The system comprises a clamper (12) for clamping a fractured rock mass (11), a to-be-detected solution bottle (22) which isconnected with a first end cap (13) through a water inlet pipe (21), a high-pressure metering pump a (23) which is arranged between the to-be-measured solution bottle (22) and the first end cap (13),a to-be-tested gas tank (32) which is connected with the first end cap (13) through a gas inlet pipe (31), a vacuum pump (33) which is arranged between the to-be-tested gas tank (32) and the first end cap (13), a water-gas separation device (25), a high-pressure metering pump b (26) and a liquid collecting bottle (27) which are sequentially connected with a second end cap (14) through a water outlet pipe (24), and a booster pump which is controlled with a test box (1). The booster pump is controlled to load the pressure, the temperature control device controls the temperature of the test box,the high-pressure metering pump is adopted for automatic metering, real-time dynamic monitoring is achieved, fracture unsaturated hydraulic parameters in the true sense can be measured, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of rock mass seepage, in particular to a rock mass fissure unsaturated seepage test system. Background technique [0002] Rock mass is a discontinuous medium composed of complete rock blocks and randomly distributed fissures. Unlike the porous medium of soil, the main seepage channel of rock mass is the fissure network between rock blocks, and the seepage of rock mass is mainly affected by the cracks. influences. According to the physical characteristics of seepage, seepage in fractured rock mass is usually divided into saturated seepage and unsaturated seepage. In many fields of energy, environment and engineering applications, such as rock slope landslides caused by rainfall, deep burial of nuclear waste, secondary oil and gas recovery, etc., all involve the study of unsaturated seepage and multiphase seepage in fractured rock mass. [0003] Single fracture is the basic unit of fracture network. Therefor...
