Dynamic Model of the Zonal Disintegration of Rock Surrounding a Deep Spherical Cavity
It is assumed that a deep spherical cavity is subjected to in situ stress at infinity, and the excavation process of the deep spherical cavity is treated like the decrease of pressure applied on its internal boundary. Trigonometric functions and hyperbolic cosine and sine functions are used in the scalar curvature. A non-Euclidean dynamic kinematic equation based on the strain incompatibility condition is derived. Laplace transformation and residue theory are used to deduce the stress fields. The strength criterion of the deep rock masses is applied to determine the number and magnitude of fractured zones and nonfractured zones of the surrounding rock masses around a deep spherical cavity.
