Embodiment approach 1
[0039] figure 1 It is a three-dimensional diagram of the temperature-pressure-osmotic pressure coupled bidirectional electromagnetic loading triaxial SHPB test system. The test device is placed on the support platform 1, which is mainly composed of an electromagnetic pulse emission system, an axial pressure servo control loading system, a confining pressure loading device and its servo control. It consists of loading system, temperature control system, osmotic pressure loading system, rod system and data monitoring and acquisition system. The test system is centered on the test sample 29 (such as image 3 shown), arranged symmetrically. Among them, the left axial load fixed baffle 2 and the right axial load fixed baffle 11 are respectively fixed on the left and right ends of the support platform 1, and the center and surroundings are respectively provided with central mounting holes and peripheral mounting holes, and the left axial load The oil cylinder 3 and the right axial...

[0043] Best Implementation Mode 2: Dynamic Impact Test Study on Fully Saturated Sandstone Samples Under Temperature-Pressure-Osmotic Pressure Coupling Triaxial Loading
[0044] The relevant equipment of the test system is as follows: Figure 1-3 The connection mode shown is placed on the support platform 1 whose length, width and height are 6m, 0.6m and 1m respectively. Arranged on the support platform 1 in a left-right symmetrical manner, first place the left axially loaded fixed baffle 2 with a width, height and thickness of 600mm, 400mm and 50mm respectively on the left end of the support platform 1, where the diameter and length are 250mm and 50mm respectively. The 200mm left axial pressure loading cylinder 3 passes through the center mounting hole of the left axial pressure loading fixed baffle 2, and is welded with it to form an integral structure. The diameter of the left axial pressure loading piston 4 is 100mm, and the piston stroke length is 200mm , through the pres...
