Embodiment Construction
[0027] The present invention will be further described below in conjunction with accompanying drawing.
[0028] refer to Figure 1 ~ Figure 3 , a kind of multi-cylinder pushing method of the shear test of large-scale rock mass structural surface based on corbel structure, described method comprises the following steps:
[0029] (1) According to the formulation and maintenance specifications of large-scale concrete samples, use cuboid steel molds to cast large-scale samples under the rock mass structure surface, and the length, width, and height of the samples are L, W, and H;
[0030] (2) According to the size of the sample on the structural surface of the rock mass, a concrete pouring steel mold with a special structure is designed. figure 1 As shown, the overall shape is a cuboid, with N pairs of protruding small cuboid structures on both sides, N is an integer, and N≥2;
[0031] (3) Utilize welding technology to fix N blocks of rectangular parallelepiped steel plates in t...
