Abstract: | This paper presents the relationship between borehole break-ellipseand the earth stress,discusses the measuring method of a four-arm dip-meter,the identification criteria of break-ellipse and the procedure ofdata processing.Result showes that the mean orientation of the transverselong axis of break-ellipse in this area is N 5°W,and the thus determinedorientation of maximum horizontal principal stress is N 85°E. |
