断层形变趋势变化研究--垂直形变趋势累积率Dc值

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

Study of trend variation of fault deformation-Vertical deformation trend accumulation rate Dc

By analyzing features of across fault measurement,the trend components of deformation can reflect the strength of strain energy accumulation in regional area.On that,the vertical deformation trend accumulation rate D c is build up,and corresponding formula are derived,and their physical meaning are discussed.The calculating results shows that the index can reflect background active strength of regional crust,and is sensitive to medium strong earthquakes.It has some applying value.
