Abstract
Rock stress determination by means of the overcoring method. Part 2: Borehole deformation gauges. Recommendation no. 14 (revised) of the Commission on Rock Testing of the DGGT. The Commission on Rock Testing of the Deutsche Gesellschaft für Geotechnik e. V. is compiling suggestions for rock mechanical laboratory and field tests as well as for monitoring rocks and geotechnical structures on-site. The presented revision of recommendation No. 14 covers the determination of rock stresses by means of overcoring tests and considers the development of this method since the publication of recommendation No. 14 in 1990 [1]. Further, requirements for the measuring instruments and the procedures regarding the execution and evaluation of these tests are specified. Reference is made to the ISRM Suggested Methods in which overcoring tests are dealt with [2, 3]. Recommendation No. 14 is divided into two parts. The first part deals with overcoring tests using triaxial strain cells. This second part covers overcoring tests using borehole deformation gauges.
