摘要
提出了一种用很轻很细的线 ,以很小的拉力组成的轻倒垂系统 ,配合垂线摆动阻尼器 ,可以达到较高的垂准精度。用这种垂准系统建立的高度较大的垂准基线 ,可以用于超高层建筑物施工和变形监测。
This paper suggested a light invert plummet system formed by an extremely light and thin line and slightly pulling force. With vertical line sway damper, it can reach more precise in vertical collimation. The vertical datum line set up by this system can be used to monitor deformation of the various building.
