The paper introduces the researching ways such as seismic survey , geo-stress measurement, geodetic survey, structure geology, petrologic limited strain measurement and balance section, etc. . In respect of the content, historical analysis is emphasized. The internal relations and regional distribution of stress data are needed to be realized by simulated test, the purpose of which is ultimately to draw a series of stress maps to show the ontline of distribution and variation of regional stress field, and the position, where may be broken. Last, the author suggests three principles to check the accuracy and reliability of simulating results.
