The pressure exerted on the support due to the deformation or collapse of the surrounding rock after tunnel excavation is known as rock pressure. Under the action of loads, when the lining deforms outward, it encounters resistance from the surrounding rock; this force exerted by the surrounding rock to resist the deformation of the lining is known as the elastic resistance of the surrounding rock. Rock pressure is the primary force acting on the lining, whereas elastic resistance is a reactive force that is conditional.

1. Elastic resistance is the restraining force exerted by the surrounding rock on the support structure, resulting from the deformation of the support structure in the direction toward the surrounding rock. Its function is to limit the deformation of the lining, improve the stress conditions of the lining, and enhance the load-bearing capacity of the lining structure. 2. Rock pressure, also known as surrounding rock pressure, refers to the pressure exerted by the surrounding rock of a chamber on its supporting structures. Therefore, the two can be understood as a pair of action and reaction forces.

Rock pressure is the primary force acting on the lining, whereas elastic resistance is a secondary force that is conditional. The important factor for considering the elastic resistance of the surrounding rock is the bearing capacity of the rock itself, whereas the key condition for fully utilizing this elastic resistance is the degree of contact between the surrounding rock and the lining. The effect of elastic resistance shows that the surrounding rock can share the loads with the lining, thereby reducing the internal forces in the lining; this is advantageous for the working condition of the lining.
