摘要：
A flow sheet and strategy for estimation of the Best Estimate Rock Stress Model (BERSM) is proposed. Extracted information from existing databases, geological data at the site and from the region, and information from boreholes and drill cores are the input to the model. Establishment of BERSM is recommended prior to any in situ stress measurement. Results from BERSM and one or several of the stress measurement techniques plus additional stress information are used in the Integrated Stress Determination Method (ISDM). Numerical rock stress models can assist in explaining the virgin stress field and together with the results of the stress measurements and ISDM enhance the quality of the Final Rock Stress Model (FRSM). Variability and uncertainty of the results provided by the different models are discussed.
