通过对跨断层测量特点的分析,提出断层运动中趋势性成分具有反映区域地壳形变及应变能累积程度的意义。据此建立形变趋势累积率的概念,推导了相应的计算公式并对其性质及物理意义作了初步解释。震例计算表明,该指标能够反映区域地壳的背景活动强度,对中强地震亦具有较强的敏感性。具有一定的实用价值
Based on the analysis of the characteristics of the cross-fault survey, it is proposed that the trend components in the fault movement have the meaning of reflecting the crustal deformation and the accumulation of strain energy in the region. Based on this, the concept of the cumulative rate of deformation trend is established and the corresponding calculation formulas are deduced. The initial interpretation of the nature and the physical meaning is made. The earthquake example shows that this indicator can reflect the background activity intensity of the regional crust and also has a strong sensitivity to moderately strong earthquakes. Has a certain practical value
