The paper introduces and presents instances of application of methodologies for analysis of the stress field obtained from the results of in situ stress measurements using the overcoring, hydraulic fracturing and flat jacks methods. These methodologies integrate all stress measurements, and use numerical models of the rock mass that represent the ground topography and the underground excavations, so that the most likely stress field in the zone of interest for the design of several large underground structures is obtained.
