Embodiment Construction
[0045] figure 1 Shows the known conditions of the tunnel and underground space: H is the buried depth, α is the half-width of the hair hole, α 1 is the half-width of the stratum sliding surface, y is the height of the hole, L is the length of the subsidence soil column, that is, the length from the hole mouth to the face of the tunnel, Z is the thickness of the soil column unit,
[0046] The application method of the present invention is as figure 2 Shown: According to figure 1 Given the known conditions provided, the following parameters are obtained: subsidence soil column aspect ratio n, depth influence coefficient n', n'=2n / (1+2n);
[0047] Then judge the shape of the cavern according to the aspect ratio n of the subsidence soil column and the influence coefficient n′ of the depth;
[0048] And according to the geological conditions of the tunnel and underground space and the classification of the surrounding rock, the physical parameters are determined: cohesion c o...
