Embodiment Construction
[0047] The present invention will be described in more detail below in conjunction with the accompanying drawings.
[0048] Rock mass weathering of the present invention, the numerical discrimination method of unloading comprise the following steps:
[0049] 1. Rock Mass Acoustic Test
[0050] In the exploration tunnel excavated by geological survey, the acoustic wave instrument is used to test the acoustic wave on the rock mass of the tunnel wall; the testing method adopts the surface acoustic wave detection flat measurement method:
[0051] The sound wave test line is arranged along the waistline 1 of the tunnel wall, and on the waistline 1 of the tunnel wall, a sound wave test point 3 is arranged every two meters, and the test points 3 are numbered, and the position of each number is recorded, such as figure 1 shown;
[0052] The transducer is used to excite, and the transmitting and receiving transducers are aligned with the test point in turn, that is, the distance betw...
