Embodiment Construction
[0021] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0022] see figure 1 , 2 , a horizontal triaxial tension-compression tester, including a test platform 16, the test platform 16 is provided with an AC motor 1 as a loading device, the maximum axial force provided by the AC motor 1 can reach 300kg in tension and compression, and the maximum load The displacement range is ±20mm, and the loading deformation rate is 0.00155mm / min~0.375mm / min, which can meet the requirements of triaxial tension, compression and compression-tension combined tests on soil under general conditions. The power of AC motor 1 The output end is connected with the rigid loading rod 5, which can realize the uniform and stable loading in the front and rear directions. The force sensor 2 is arranged on the rigid loading rod 5, and the rigid loading rod 5 is connected with one end of the front ...
