| 摘 要： | 我国城市快速发展,人口急剧增加,地下水超量抽汲,需要以新思路、新方法进行城市大地形变测量,实践证实DInSAR+倾斜摄影技术更具优势。应用DInSAR及改进的沉降监测技术取得H市两个时间段地面形变监测成果后,经精密水准测量检验,证实结果可靠。倾斜摄影技术不断进步,经大量实践,已成为城市形变监测的又一选择。应用DInSAR+倾斜摄影进行城市形变监测,打破了传统形变测量的手段和理念,实现了与基础成果的全景比对或相同点位真三维对比,还可对城市的点、面、体,局部或全方位进行形变监测,监测成果可互为验证,且效率高、精度高、成本低,本文采用该方法实现了试点区的监测工作。

| Abstract: | The rapid development of Chinese cities and increasing population cause excessive pumping of groundwater,which requires new ideas and methods for the measurement of urban geodetic deformation.Practice confirms that DInSAR+oblique photography tech-nology has more advantages.The application of DInSAR and improved subsidence monitoring technology are applied to monitor the ground deformation of two time periods in H City,and the results are proved to be reliable by precise leveling measurement.As the continuous improvement and practice of oblique photography technology,it has become another reliable technology for urban deforma-tion monitoring.Different from traditional methods and concepts of deformation measurement,the application of DInSAR+oblique pho-tography technology for urban deformation monitoring achieves a panoramic comparison with the fundamental results and a true three-dimensional comparison of the same point.It monitors the deformation of cities from geological dot,plane,body,local area or omni-direction,and the monitoring results can be mutually verified in accordance with high efficiency,high precision and low cost.The practical design of monitoring work in the experimental area also drawn in this paper. |
