Embodiment Construction
[0052] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0053] The measurement method of the shear area in the direct shear test of the rock mass structural surface provided by the invention, see Figure 1 to Figure 9 , including the following steps:
[0054] (1) Photo collection of structural surface of rock mass:
[0055]Place the cut rock mass structural surface in a bright place, and use an ordinary digital camera to take pictures of the cut rock mass structural surface surface. Before taking pictures, it is required to clean the surface of the rock mass structural surface, and at the same time use 1 mm A scale for accuracy is placed alongside as a reference, and the scale should be included in the picture. see Figure 2-Figure 3 When taking pictures, the lens of the digital camera 1 focuses vertically on the rock mass structural surface 2, and selects the close-range mode for shooting to avoid error...
