| Abstract: | The relationship of inferring the state of additional strain by additional principal stress ratio was derived from physical formula of elastodynamics and the relation between additional stress field and fault activities was analyzed.Based on the calculation results of additional principal stress ratio for the ground stress stations in Gansu Province from 1983 to 1995,the correlation of additional principal stress ratio with moderate earthquakes was studied,the seismogenic mechanisms were further discussed and some preliminary results were got. |
