The reaction of the Earth’s surface to twisting and normal loads moving through the tunnel

Abstract

The problem of the action on the surface of a circular cylindrical cavity located in an elastic half-space (array) uniformly moving along its forming normal and twisting loads is solved. Dynamic equations of elasticity theory are used to describe the motion of the array. On the basis of the obtained solution, the stress-strain state of the Earth’s surface is investigated under the action of axisymmetric loads of this type uniformly moving along an unsupported tunnel of shallow laying
