给出了半无限介质中任意倾角的多个已发震矩形断层对邻近任意倾角的潜在活断层共同作用的合应力的解析表达式，从而可以计算震后合应力的调整值，为判断潜在活断层的稳定性提供依据。合应力Ｓｒ中既包括了作用在断层面上的正应力，又包括了断层面上的剪应力，它比单独用一个应力描述应力场更有效。最后，用１９７３年２月６日炉霍地震后的实际震例说明了地震断层错动对周围孕震区的触发作用
The analytic expressions of the combined forces of multiple seismogenic faults of arbitrary dip angle in a semi-infinite medium with potential active faults near any inclination are given, so as to calculate the adjustment value of the resultant stress after the earthquake. In order to determine the potential survival Fault stability provided the basis. The combined stress Sr includes both the normal stress acting on the fault plane and the shear stress on the fault plane, which is more effective than using a single stress to describe the stress field. Finally, the actual earthquakes after the Huohuo earthquake on February 6, 1973 are used to illustrate the triggering effect of the earthquake fault on the surrounding seismogenic zone
