RESEARCH ON VERTICAL STABILITY OF LIQIZHUANG ??
BEDROCK POINT |
| |
| Abstract: | The relatively stable reference point or benchmarkand was finded according to the concept of “relatively stable” and it was used to analize stability of the leveling points and evolution of the motion state with the data from the Capital Circle Vertical Deformation Monitoring Network and the Control Land Subsidence Monitoring Network in Tianjin.The results combined with the analysis results of GPS data indicate that Liqizhuang bedrock point is sinking at 2.5 mm/a in the recent years. |
