[0037] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
[0038] An experimental method for tensioning of columnar joint structural surface. According to the characteristics of columnar jointed rock mass, the test device of changing pressure to tension is redesigned. Mainly reflected in: the device mainly includes three parts: pressure bearing device, fixed sample placement device, and sample bonding device;
[0039] Among them, the pressure bearing device includes three parts: the bearing plate 5, the adhesive plate 13 at the lower end of the sample, and the connecting rod 6. The bearing plate 5 is mainly used to bear the load applied by the press, and the adhesive plate 13 is mainly used to hold the sample. The lower end is connected with the bonding plate, and the connecting rod 6 connects the bearing plate with the bonding plate.
[0040] The fixed sample device runs through the three parts of the ir...
