The Interpretation of Stress Measured Results by Eigenanalysis
Eigenanalysis법(法)에 의(依)한 현지응력(現地應力) 측정치(測定値)의 해석(解析)
Abstract
A strain gage relief technique was used to determine the magnitude and directions of a virgin principal stresses, but the values measured in the same borehole are always not consistent. This paper has shown the use of the eigen analysis to achieve precise and reliable principal stress from measured values. The best fit stress ellipsoid to the data has been obtained through consideration of direction cosine of each principal stress.
