摘要

为研究乌克兰境内近期地壳应变变形，建立了202个永久GNSS站组成的区域GNSS网络。利用伯尔尼GNSS软件对1997年12月7日至2017年1月28日的GNSS观测数据进行收集和处理。5.2根据EUREF永久全球导航卫星系统网络中央局的建议。在此基础上，利用Bernese GNSS软件进行了速度矢量估计。5.2为以后的变形计算。特别地，得到了变形椭圆、旋转椭圆、最大剪切应变椭圆和变形面积椭圆。由于水平延伸和旋转速率的差异，该区域被分为两个主要块。第一个地块显示了东北方向普遍存在的压缩。第二街区的情况是双向拉伸。得到的结果可以表明存在一些力，这些力可能对研究区域产生影响。

Investigation of Deformations of the Earth Crust on the Territory of Ukraine Using a Gnss Observations

Abstract A regional GNSS network consisting of 202 permanent GNSS stations established to study the recent crustal strain deformation in the Ukrainian territory. The GNSS observations (from December 7, 1997 to January 28, 2017) collected and processed using Bernese GNSS Software ver. 5.2 in accordance with the recommendations of the Central Bureau of the EUREF Permanent GNSS Network. Based on the above results the velocity vectors were estimated using Bernese GNSS Software ver. 5.2 for the future calculation of deformation. In particular, ellipses of distortion, rotation, maximum shear strain, and deformation area are obtained. Due to the differences in rate of the horizontal extension and rotation the area is divided in two main blocks. The first block shows compression that prevails in the North-East direction. Stretch in both directions is prevailing on second block. The obtained results can indicate the presence of some force which could effect on the study area.
