| Abstract: | In China, a lot of data derived from focal mechanism solutions, and especially, from overcoring and hydrofracturing stress
measurements, as well as borehole breakouts carried out for various aims have contributed to understanding of the state of
the crustal stress. We conducted everin situ stress measurements in a borehole with different methods, for the sake of comparison of various measuring techniques. Furthermore,
we carried out measurements in different borehole with one or two kinds of techniques. All the observations taken out in these
ways showed little variations. So we believe that the data obtained by the techniques can be used to study the tectonic stress
field of certain region and thein situ state of the crustal stress.
