Embodiment Construction
[0044] The structural features of the present invention will now be described in detail in conjunction with the accompanying drawings.
[0045] see figure 1 , the preparation method of the soft rock disintegration test sample under the joint action of wet-dry alternation and stress, the steps are as follows:
[0046] Step 1: Determine the size of the cuboid sample to be prepared:
[0047] According to the disintegration test requirements and the characteristics of the test device, determine the specific size of the disintegration test sample. For example, when using a disintegration test device under the combined action of wet-dry alternation and stress, if the net size of the cuboid sample box in the device is 200×200×100mm, then the disintegration sample is a cuboid and its size is 200×200×100mm.
[0048] Step 2: Make a cuboid (including cube) mold 3; the mold 3 is used to make a cuboid (including cube) sample; determine the internal size of the mold 3 according to the si...
