2008 年 5 月 12 日女士 8.0 Wenchuan 地震在三个峡区域在井的水层次引起了著名变化。这个工作在含水土层参数在水水平和变化检验在这些 coseismic 变化之间的关系。在有对地球潮的好回答的区域的三口井为分析被选择。到 2008 年 6 月的从 2 月的水级的数据被用来计算含水土层 transmissivity,渗透和岩石的特定的存储,并且分析在井和他们的含水土层参数的 coseismic 回答之间的关系。结果证明 Wenchuan 地震更加改变了这些参数,从而控制水的 co- 和 postseismic 变化水平。在地震以前的这些参数的价值线性地在水水平与 coseismic 变化的振幅被联系。越大含水土层 transmissivity,越多显著水里的 coseismic 变化水平。在地震期间,在参数被发现在水水平与 coseismic 变化被联系的含水土层变化,与当在水水平的 coseismic 变化更大时,发生的更大的变化。构造背景在水水平有对 co- 和 postseismic 变化的影响的某个度。差错地区的渗透结构看起来在水水平决定 coseismic 变化的方式。而且,看起来,在地下水更容易收敛的井的水水平能恢复更快的列在后面地震。从这研究的卓见帮助改进地震引起的水级的变化的特征的理解。

英文摘要:

The 12 May 2008 Ms 8.0 Wenchuan earthquake caused notable changes in the water levels of wells in the Three Gorges area. This work examines the relationship between these coseismic changes in water level and the changes in aquifer parameters. Three wells in the area with good responses to earth tide were chosen for analysis. Water-level data from February to June 2008 were used to calculate the aquifer transmissivity, permeability and specific storage of the rocks, and analyze the relationship between the coseismic responses of the wells and their aquifer parameters. The results show that the Wenchuan earthquake changed these parameters considerably, thereby controlling co- and postseismic variations of water level. The values of these parameters prior to the earthquake are linearly related with the amplitudes of coseismic variations in water level. The larger the aquifer transmissivity, the more remarkable the coseismic change in water level. During the earthquake, changes in aquifer parameters were found to be associated with coseismic variations in water level, with the larger changes occurring when the coseismic variation in water level was larger. The tectonic setting has a certain degree of influence on the co- and postseismic changes in water level. The permeability structures of the fault zone appear to determine the manner of coseismic variation in water level. Moreover, it seems that the water level in wells where groundwater converges more easily can recover faster following an earthquake. Insight from this study helps to improve understanding of the characteristics of water-level changes caused by earthquakes.
