某区水库大坝近期形变特征研究

STUDY ON RECENT DEFORMATION CHARACTERISTIC'S OF RESERVOIR'S DAM IN SOME REGION

通过利用GPS和水准测量手段对某区水库大坝表面运动进行监测,获取大量的野外监测数据。通过内业计算得出每期的大坝各变形点的三维坐标,并结合、利用近3期的数据资料对比,求出各点的形变量。最终通过计算、分析得出水库主坝、东副坝及北副坝3个坝体的稳定性。

The surface motion of reservior＇s dam in some region is monitored using GPS and leveling, and obtain large numbers monitoring datum. Computing the datum to obtain three dimensions coordinates of every deformation point in the reservoir＇s dam, contrasting the datum of 3 times to obtain the deformation quantity of every point. In the end, the stability of main dam, eastern secondary dam and northern secondary dam are obtainned by computing and analysis.
