Soil permeability coefficient testing system and method

The invention provides a soil permeability coefficient testing system and method, and relates to the technical field of soil permeability coefficient determination, and the system comprises a rock-soil bearing device, a water supplementing device, a cold bath device, a fluorescence monitoring device and a data acquisition device. The water replenishing device is used for conveying water into the soil sample to discharge air in the soil sample and can automatically replenish water; the cold bath device is used for adjusting the temperature of the soil sample to simulate a freezing and thawing cycle process; the fluorescence monitoring device comprises a fluorescent agent injector and an image acquisition mechanism. The data acquisition device comprises a data acquisition instrument, a plurality of moisture sensors, a plurality of pore water pressure sensors and a plurality of temperature sensors, wherein the moisture sensors, the pore water pressure sensors and the temperature sensors are in communication conn
