Test device and test method for rock soil splitting test

The invention discloses a test device and a test method for a rock soil splitting test. The test device comprises a rack, a lower pedestal, an upper pedestal, and a wedging type loading mechanism. Thewedging type loading mechanism comprises a horizontal mounting shaft, a first wedging plate, a second wedging plate, and a drive motor. A gear rack transmission mechanism is arranged between the drive motor and the first, the second wedging plate. An angle measuring ruler is mounted on the first wedging plate. The test method comprises the following steps: 1, preparing a required cylindrical rocksoil sample; 2, mounting the cylindrical rock soil sample; 3, loading the cylindrical rock soil sample; 4, performing multiple groups of tests by repeating the steps of 1 to 3 to obtain multiple groups of test results; and 5, observing and analyzing the multiple groups of test results to summarize the rule of cracking directions of cracks. According to the test device and the test method for therock soil splitting test, a
