并置VLBI站相对形变率及其与VTRF2005结果的比较

对杨志根等人在2005年估计的全球6个并置VLBI站的相对形变率(特别是相对垂直形变率)结果与最近的VLBI全球解VTRF2005的相应结果作了比较。结果表明,北美Greenbank的NRAO20和NRAO85_3两个VLBI站之间每年3—4mm的相对垂直形变率和Westford的WEST- FORD和HAYSTACK两个VLBI站间每年1-2mm的相应结果可以进一步得到肯定;太平洋夏威夷岛的KOKEE和KAUAI两个VLBI站每年2～5mm的相对水平形变率和日本鹿岛的KASHIMA和KASHIM34两个VLBI站间每年1-2mm的相应结果也可以得到确认。然而,每年2—4mm的KASHIMA和KASHIM34站间的相对垂直形变率结果,在过去所有观测研究的结果中都被基本肯定,在VTRF2005中的结果中却几乎消失了,对其中可能的原因作了讨论。此外,对北美的FD-VL- BA和HRASO85两个VLBI站间的相对垂直形变率仍不能肯定,在不同的全球解中,FD-VLBA站的形变率解结果是基本稳定的,而HRASO85站在VTRF2005中的垂直形变率结果为(2．61±3．91) mm／a,与估计的结果符号相反,并且比在VTRF2003中的相应结果大了2．2mm／a,估计误差也大了近7倍。有关的结果还有待采用更新的资料进行讨论。     

面向水文数据的自动化信息整合与分析

基于SL324-2005标准表结构的水文数据库为水文数据的管理带来便利,但是由于该数据库的设计是面向数据管理的,不易于用户读取、理解和充分利用。基于以上问题,设计并构建了一个面向水文数据整合的实验模型,通过对水文数据库的解释和转化,使水文数据以一种更理想、更符合人的认知习惯的方式呈现给用户,有效实现了水文数据的定向提取、管理、表达和分析,为基于水文数据的人机交互和统计分析奠定了重要基础。

The role of the Kazakhstan orocline in the late Paleozoic amalgamation of Eurasia

After the 2005 Kashmir earthquake, we mapped surface ground fractures in Tangdhar, Uri, Rajouri and Punch sectors and liquefaction features in Jammu area lying close to the eastern side of the Line of Control (LOC) in Kashmir, India. The NW trending ground fractures occurred largely in the hanging wall zone of the southeastern extension of the causative fault in Tangdhar and Uri sectors. The principal compressive stress deduced from the earthquake induced ground fractures is oriented at N10°, whereas the causative Balakot–Bagh fault strikes 330°. The fault-plane solution indicates primarily SW thrusting of the causative fault with a component of strike–slip motion. The ground fractures reflect pronounced strike–slip together with some tensile component. The Tangdhar area showing left-lateral strike–slip motion lies on the hanging wall, and the Uri region showing right-lateral strike–slip movement is located towards the southeastern extension of the causative fault zone. The shear fractures are related to static stress that was responsible for the failure of causative fault. The tensile fractures with offsets are attributed to combination of both static and dynamic stresses, and the fractures and openings without offsets owe their origin due to dynamic stress. In Punch–Rajouri and Jammu area, which lies on the footwall, the fractures and liquefactions were generated by dynamic stress. The occurrence of liquefaction features in the out board part of the Himalayan range front near Jammu is suggestive of stress transfer  230 km southeast of the epicenter. The Balakot–Bagh Fault (BBF), the Muzaffarabad anticline, the rupture zone of causative fault and the zone of aftershocks — all are aligned in a  25 km wide belt along the NW–SE trending regional Himalayan strike of Kashmir region and lying between the MBT and the Riasi Thrust (Murree Thrust), suggesting a seismogenic zone that may propagate towards the southeast to trigger an earthquake in the eastern part of the Kashmir region.
