The present invention proposes a method for preparing polar region water-containing simulated lunar soil based on ice-soil mixing, which belongs to the technical field of simulated lunar soil preparation. It solves the problem that in the freezing process of water ice in the previous profile sample, the freezing rate of the sample boundary will be stronger than that of the sample interior, causing the sample boundary temperature to be lower than the sample center. Due to the principle of cold end migration of water, the water inside the sample will migrate to the surroundings, causing the water content of the sample boundary to be higher than that of the sample center. The water content of the entire sample is not uniform, and the strength and hardness of samples with different water contents are also different. As a result, the stress, drilling power and water content of each drill during the sample drilling process in the later test cannot be unified, and the variables cannot be controlled, resulting in the drilling test data obtained in the later stage having no reference value. Through the sample preparation process of the present invention, the ice is frozen and crushed separately and then evenly mixed with the dry and cooled simulated lunar soil sample, so that the water content of each part of the entire sample is relatively uniform and reaches a controllable level.
