Soil synchrotron radiation X light rotating triaxial real time observation method and system thereof

A soil synchrotron radiation X light rotating triaxial real time observation method comprises the following steps: a pressure source supplies a constant confining pressure to a triaxial apparatus pressure chamber, and applies the pressure to soil in the pressure chamber; and the soil in the triaxial apparatus pressure chamber is arranged under a synchrotron radiation X light source, the triaxial apparatus pressure chamber controls running of a stepping motor to increase or reduce the transmission ratio of a mechanical loading device, the axial pressure of the triaxial apparatus pressure chamber is increased or reduced step by step to supply different loads of the constant confining pressure to the soil, the triaxial apparatus pressure chamber rotates around the axis of the pressure chamber cylinder, and the synchrotron radiation X light source observes the three-dimensional microstructure of the soil in a real-time lossless manner to obtain the X light thrust sequence picture of the microstructure in the soil
