3. 2. New developments in hydrofracturing stress measurement techniques and a comparison to the HTPF method

   Författare :Christer Ljunggren; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Sammanfattning : This thesis describes two hydraulic methods for rock stress measurements; hydraulic fracturing and hydraulic tests on pre-existing fractures (the HTPF method). It includes theories to evaluate stress field information for somewhat extraordinary stress and field situations, experimental investigations and field measurements. LÄS MER

4. 3. New developments of the Integrated Stress Determination Method and application to the Äspö Hrad Rock Laboratory, Sweden

   Författare :Daniel Ask; KTH; []
   Nyckelord :Integration; Rock Stress; ISDM; Äspö HRL;

   Sammanfattning : This thesis presents new developments of the IntegratedStress Determination Method (ISDM) with application to the AspoHard Rock Laboratory (HRL), Oskarshamn, Sweden. The newdevelopments involve a 12-parameter representation of theregional stress field in the rock mass. LÄS MER
