摘要
本文在讨论琼州海峡及邻域断裂对地震活动性的影响时,首次引入稳定度(β)的概念。它是指在库伦破裂准则下材料稳定程度的数字表征,其表达式为它对评价材料(或某一区域地质体)有无断裂的稳定程度具有定量研究的意义。本文通过计算海峡及邻域断裂的△β值后,得出△β值的增减对地震活动的影响跟前人所总结的地震活动性规律是相吻合的。
In studying the influence of faulting on earthquake activities, the authors defined the degree of stability β=1+(?)which is the quantitative cha
racterization of the stability of materials under the law of Coulomb crack. It is useful for evaluating the resistance of a geological block against faulting. According to the △β values in the strait, the authors summarized the relationship of △β values with seismic activit. The conclusions are consistant with those of previous workers.
