| THE RESEARCH ON THE RECENT STRESS FIELD AND REGIONAL STABILITY IN THE BEIJING AREA |
| The stress is an important factor in the research on the crustal stability of a given region. Its occurring and developing is closely related to the earthquake and fault action. So it's an important method to evaluate the crustal stability of a given region from the stress. Mathematical stimulating model has been established according to the seismic and geological structure and recent crustal acting and so on in Beijing area (Fig. 1). On the above-mentioned method the authors calcaulated the field of recent structural stress and the fields of regulating influence as the increasing of fractural action in Beijing area(Fig. 4-Fig. 10), and established the field of comprehensive reguting influence as the increasing of fractural action on the basis of every field of regulating influence (Fig. 11). The authors also analysis and compare the relative grade of crustal stability of Beijing area and the relative grade of crustal stability of Beijing city in Beijing area, and get a conclusion that the increasing of Nankao-Sunhe fault action is rather affecting to the crustal stability of Beijing city. |
