Embodiment 1
[0048] One, embodiment 1: test device
[0049] 1. Overall
[0050] Such as figure 1 , 2 , the test device includes a soil sample 00, a fault soil model instrument 10, a fault plane 20, a continuously variable transmission 30, a power transmission system 40, a support lever 50, an earth pressure cell 60, a real-time monitor 70, a data acquisition system 80 and dial gauge 90;
[0051] The soil sample 00 in the fault soil model instrument 10 is divided into two parts, the fault hanging wall 21 and the fault foot wall 22, through the fault surface 20;
[0052] The first continuously variable transmission 31, the first power transmission system 41, the support lever 50 and the fault upper plate 21 are sequentially connected to provide displacement power for the fault upper plate 21; the second continuously variable transmission 32, the second power transmission system 42 It is sequentially connected with the fault footwall 22 to provide displacement power for the fault footwal...
Embodiment 2
[0082] Two, embodiment 2: test method
[0083] In step ①
[0084] The height of the fault hanging wall is 0.80m, the slope bottom of the fault footwall is 0.60m away from the bottom of the model, the fault angle is 75°, and the thickness is 0.03m. The coefficient of friction is 0.5.
[0085] In step ④
[0086] Adjust the support lever 50 so that the direction of the transmission force of the first power transmission system 41 is consistent with the fault angle, that is, 75°;
[0087] Power is applied, and the data acquisition device is turned on at the same time. According to the movement mode of the fault, relevant settings are made to the parameters in the control panel of the first continuously variable transmission 31, so that the fault hanging wall 21 moves along the fault plane 20 at a speed of 0.2 cm / s. Speed up movement.
