工程水准复测垂直形变分析

ANALYSIS OF ENGINEERING RE-LEVELING VERTICAL DEFORMATION

  • 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 positive 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.
