Displacement Solution of Salt Cavern with Shear Dilatation Behavior Based on Hoek-Brown Strength Criterion

Table 1

Summary of the displacements in the plastic zone.

Geometric equations
Displacement in the plastic zone in a compact form
	The elastic strain in the plastic zone is a constant value, which equals to the elastic strain at the elastic-plastic interface in the elastic zone
	The elastic strain in the plastic zone is a variable, which abides by Hooke’s law
