Abstract

The stress-strain state in rocks around an excavation is assessed by the values of stresses “at infinity”, i.e., it is required to know stress distribution in an intact rock mass. The authors propose a new method of the stress-strain state assessment for an arbitrary cross-section excavation based on direct measurement of displacements of the excavation walls, using the Kolosov-Muskhelishvili formulas. Under analysis are the excavations shaped as circular and elliptical cylinders.
