Recent activities of ground fissures in Xi'an hot well water level relationship
Near joints, the following existing uneven buried fault would be more prominent. And may further trigger the fault creep. This is also why the Xi'an earth fissure zone coincides with the ground subsidence, and the pumping of a settlement of the crack displacement constitutes a major component of the interpretation. However, through analysis of land subsidence and ground fissures dynamic of the whole process (Figure 3), we can see the impact of pumping settlement failed to cover up the cracks and the essential relationship between tectonic activity, not in general change the tectonic stress field to split the role of active control. Reflects the impact of land subsidence on the ground there are structural cracks in the dynamic modulation. That the performance of an active period in the tectonic subsidence superimposed on to crack a marked improvement activities, and tectonic activity in the quiet period, the characteristics of superposition was significantly decreased,,,, two hundred twenty-one - I -. - I -. 1 intoxicated ... / prince Yu 3 hamlet between ground fissures and land subsidence in Xi'an Film Studio prince Yu observed that the water level the following 1520m deep aquifer pore water pressure was observed with a layer. Closed conditions set pressure system, which independent of the impact of these factors, and the pressure to pass through such means as the crust in the sensitively reflect the state of stress and strain,[link widoczny dla zalogowanych], stress and strain of rock mass in the tiny pore pressure can be reflected in changes in the ,[link widoczny dla zalogowanych], so it is a dynamic reflection of the deep tectonic activity. Deep changes in conduction to the surface and ground deformation caused by some of rock must be through the complex medium, this process will take some time, so that lags behind the ground fissure pore pressure changes. 4 Conclusion and questions hamlet to crack and the West affect water level because there is intrinsically linked, a source that they are controlled by the same, they are sensitive to regional tectonic activity window; structural characteristics of the dynamic modulation; to lag behind the deep fissure pore pressure changes reflect the stress and strain to the shallow conduction process. 10 ground fissures in Xi'an is the emergence of different periods, each of the activities of ground fissures are quite different rates, in / maggots one by one Jiaojiao-i-�� 2 of Liu Sheng and so fast; Xi'an bucket of hot water to crack Events Relationship of 73-bit crack the same way there are also differences between different sections of this paper is only the western shadow of the deep well water level and the hamlet in the middle of the recent activities of cracks in the relationship, so the conclusions reflect a general rule, it remains to be more in-depth research.
