基于数字化水位的张渤带地区构造应力场时序特征分析

Abstract

Abstract: We selected digital water level and corresponding air pressure data of 6 wells in the Zhangbo Belt area, which are continuous, stable and with obvious solid tide since 2008. These wells are Changping station well, Shunyi Banqiao well, Baodi well, Xinzhuang well, Yutian(03) well, Dahuichang well etc. We obtained porosity and volume compression coefficient between solid skeleton and water under undrained condition by the barometric efficiency and M₂ tidal factor smooth fitting. In horizontally layered one-dimensional aquifer mode, making use of partial aquifer parameters (porosity, water and solid skeleton volume compression coefficient), relationship between water level variation and aquifer vertical stress, we quantitatively analyzed the dynamic change process of tectonic stress field of the Zhangbo Belt area. The results show that Zhangbo Belt area has continued with stress enhancement activities in recent years.
