%X <p>   Permeability can reflect the long-term stability of underground structures to a certain extent, and is an important index to evaluate the long-term stability of underground structures. The data set uses nitrogen as the permeability medium, and based on the measurement of transient pressure pulse method, the triaxial tester applies different confining pressures to the sample to simulate the stress state of the underground structure, mainly recording the permeability changes of the sample under different erosion conditions under different confining pressures.
