| 摘 要： | 利用京沪高铁京津段的八期工程水准复测资料,绘制了2007年3月-2011年3月间的京津地区垂直形变图,并对京津沿线地区近期垂直形变趋势进行了分析研究.研究结果表明,2009年3月至2011年3月期间,不同地点出现了正速率变化,与以往对于这一区域负速率变化的地面沉降规律形成了一个“反向”变化,显示出区域应力场受外部干扰和影响后的变化特征.为分析研究首都圈地区今后一段时间的地壳垂直形变趋势提供依据.

| Abstract: | Using 8 periods re-leveling data of Beijing-tianjin stage of Beijing-shanghai high speed railway, this paper draws the vertical deformation map of Beijin-tianjin area during the period of 2007.3-2011.3 and analyzes the current vertical deformation changing trend along the Beijing-tianjin stage of Beijing-shanghai high speed railway. The result indicates that during the period of 2009.3-2011.3, several sites show posi- tive velocity changing which is contrary to the negative velocity changing of land subsidence before, which may indicates that the regional stress field have changed under external influences. |
