摘要
川东隔档式构造由位于四川盆地东部一系列NE-NNE向的隔档式褶皱组成,背斜系统之间是否具有水力联系,将对地下水资源的开发产生影响。根据铜锣山背斜-南温泉背斜构造条件,结合典型水样的水化学、同位素特征,讨论了背斜系统的地下水系统特征,对铜锣山背斜-南温泉背斜地下热水系统间的水力联系进行分析。分析表明:铜锣山背斜-南温泉背斜的热水补给均来自高山降雨;铜锣山背斜-南温泉背斜的纵向水力联系明显;铜锣山倾末段-南温泉背斜有一定的横向水力联系。地球水化学模拟为上述推断提供了佐证。
The ejective tectonics lying in eastern Sichuan Province is composed of NE-NNE extending folds in the eastern part of Sichuan Basin.It is not clear that whether a hydraulic connection of groundwater influences its development.We analyzed the geological tectonic of the anticline system.In combination with the hydrochemistry and isotope characteristics of the water sample,the characteristics of groundwater system is discussed,and the hydraulic connection of the hot springs system of Tongluo Mountain anticline to South hot spring anticline is analyzed.The results show that the hot spring supply comes from the precipitation of the mountain;the vertical hydraulic connection is obvious and there is a certain transverse hydraulic connection as well.The hydrochemistry simulation has verified the deduction above.
