[0040] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0041] Such as Figure 1 to Figure 6 As shown, a loading path method for determining the weakening effect of water-rock coupling in fractured rock mass specimens, the test method steps are as follows:
[0042] S1: (1), test sample preparation:
[0043]According to the laboratory specifications, the rock samples taken on site were first prepared into 5 samples with a size of φ50mm×H100mm; the test considers the influence of seepage, so it is necessary to form a fracture surface or crack in the test piece that can pass through the seepage water, so drilling is used method, drill a hole with a diameter of 5mm and a depth of 80-90mm at both ends of the test piece, and the distance between the centerlines of the two holes is 30mm. The schematic...
