本文根据断层位移测量资料进行分析,认为八宝山断裂带近二十年来有长趋势的活动。大震前有较明显的断层活动异常显示,大震时有同震活动并留有永久位移。并强调指出,对断层现今活动特征的了解,只有通过长期连续可靠的观测才能逐步加深认识,而不能用相象的应力场任意臆测。 Based on the data of fault displacement measurement, this paper argues that the Babaoshan fault zone has a long-term trend in recent 20 years. The more obvious fault activity anomalies before the earthquake show that there are coseismic activities and permanent displacements during the earthquake. And emphasized that the understanding of the features of current fault activities can only be gradually deepened through long-term continuous and reliable observations, and can not be arbitrarily speculated by using similar stress fields.
