Abstract: This paper gives a brief recommendation on developing procedure and classification of the insitu stress measurement techniques. The authors establish a simple evaluation system by the aid of the basic theory of mechanical design, and compare the functionality, economical efficiency, maneuverability and security of every examination method, and give the comprehensive evaluations at last. At the end of the article the autors point out the developing direction of the testing technique.
