- Аннотация: 1. By means of the proposed method it is possible to predict different accidental overbreaks - the most characteristic manifestation of the rock pressure on the enclosing timbering under conditions of rock of medium firmness, which agrees with the underground hydraulic construction practice. The analytical dimensions of these overbreaks in accordance with this practice turn out to be, in the depth range which is characteristic for this type of construction, somewhat smaller than those predicted in the usually applied procedures and, at the same time, they are sufficiently large so that the possibility of development of such overbreaks must be taken into account in the analysis of the enclosing timbering. 2. Analyses made for arched excavations by the procedure described in this article takes account of the additional concentration and characteristics of the distribution of stresses for arched excavations in comparison with circular. © 1991 Plenum Publishing Corporation.
