%X According to the characteristic of the mechanics performance of artificial frozen soil and experimental rules, a computer controlled system for artificially frozen soil was developed at a single testing machine. The machine can carry on tests not only for the compression strength of single axis but also for the creep strength of single axis. In the experiment system three individual loading ways were set up and allowed to be chosen according to the test demands. They are the stress control, strain control and creep test. At the same time, the system can completely assign experiment parameters according to requests and carry on the computer to control tests. The system can write down all test data, and has the outputting functions of setting up inquiry, report form and figure, etc. The key technology of the computer controlled system was introduced. A few of experiment examples were presented. The results have valuable reference meaning for studying frozen soil mechanics experiments and for manufacturing frozen soil testing machines.
