| 1 | Analysis on Tectonic Movement of the Longmenshan Fault Zone before the Wenchuan M_S 8. 0 Great Earthquake显示文摘On the basis of elastic rebound theory,using the horizontal velocity field of the Chinese mainland calculated from GPS data during three observation periods from 1999 to 2007,the velocity components that are parallel and plumb to the fault zone are calculated respectively for different periods,and then relative ground movements of two sides of the fault zone are analyzed with power function fitting and graphics. The results show that the relative ground movement shows right-lateral shear deformation before the Wenchuan MS8. 0 earthquake,and at the same time the movement was hindered by the Longmenshan fault zone. Thus,this result has positive significance for distinguishing the elastic strain energy accumulation and deformation anomaly in an earthquake preparation process,and for conducting further research on earthquake prediction. | Ping Jianjun Jiang Zaisen Feng Xiangdong Ping Caipeng Shan Lianjun Wang Xia | 2014 | Earthquake Research in China2014，28，3： | 0 |
| 2 | Impact of Grouting and Loading of Building Construction on the Water Level of Tangshan Mine Well显示文摘The water level rising rate of Tangshan mine well significantly accelerated in 2010,and the ascensional range was obviously higher than that of the same period in previous years.From the view of groundwater dynamics and loading effects,and based on the water pumping( pouring) water test model and semi-infinite elastic space theory model under uniform load,the effects of grouting and loading of nearby building construction on the well water level were analyzed. Results show that grouting at a distance of 200 ~ 700 m to the well,with amount of 2500m3 per day and duration of 270 d,can cause an 8 ~ 11 m rise of well water level; and loading of large-area building construction can cause about a 4m rise of well water level. Through the analysis of these factors,we find that the water level anomalous rising of Tangshan mine well was relevant to grouting and loading of the nearby building construction. This study provides a scientific basis for anomalous rising analysis of water level of Tangshan mine well. | Sheng Yanrui Zhang Ziguang Zhang Suxin Sun Dongxia Shan Lianjun Yin Baojun | 2014 | Earthquake Research in China2014，28，2： | 0 |
