Claim 1:
2. The method according to claim 1, wherein: the spatial axisymmetric calculation model in step 1 and related parameters are as follows:
pz—the external load borne by the ground;
p0—the horizontal load of the virgin rock stratum, p0=μ[pz+γ(h+z)]/1−μ);
γ—the gravity density of the rock-soil layer, in kN/m3;
μ—the Poisson's ratio of the rock-soil mass;
h—the thickness of the overlying stratum, in m;
R—a distance from any point to a spherical cavity center, in m.
