The application relates to a parallel intelligent pressurized triaxial sample preparation technique and belongs to the technical field of indoor geo-techniques of civil engineering. The parallel intelligent pressurized triaxial sample preparation technique includes: (1) preparing before an experiment, to be specific, determining magnitude of pressure to be applied in the experiment process and experiment-required time according to stress history, depositional conditions and particle composition of experimental soil; (2) preparing instruments; (3) placing a soil sample; (4) compacting; (5) extracting the soil sample; (6) resetting the instruments, and preparing a next sample according the steps of (1) to (5). The parallel intelligent pressurized triaxial sample preparation technique enablestriaxial sample preparation pressure and time to be intelligently controlled, enables multiple samples to be formed at a time, ensures shorter sampling time and less disturbance upon a soil sample, overcomes the defect that traditional sample tube sampling is difficult and has certain engineering applicability.
