STUDY OF THE RELATIONSHIP BETWEEN THE RECENT ACTIVITY OF XIAN GROUND FISSURE AND WATER LEVEL OF HOT WATER WELL

Based on observition data of Xiaozhai ground fissure and Xiying well's water level, the characteristics of quasi-synchroneity and relationship to phase are analyzed. Combining with the data of ground subsidence rate and seismic activity nearby, we have studied the cause of interrelation between ground fissure and Tertiary deep water, and the effect of water-pumping ground subsidence on the ground fissure.
