摘要

Orientations of in-situ horizontal principal stresses were determined by using both drilling induced borehole compressive failures (breakouts) and tensile fractures from electrical images obtained in the Hole-B of Taiwan Chelungpu-fault Drilling Project (TCDP). Overall, the orientation of the in-situ maximum horizontal principal stress SHmax is parallel to the dip direction of rock formations in the studied depth of 950-1350 m. However, S Hmax orientations in the depth of 1130 m and 1190 m seem to be perpendicular to the dip direction of the formations.
