摘要
讨论了一种针对大型拱坝多维变形的自动观测方法。该方法沿折线布置多个测点,采用激光与PSD传感技术,实现对线位移和角位移的测量,获得每个测点的多维变形数据。给出了计算公式,并介绍了实现该方法的技术方案。该方法解决了大型拱坝多维变形自动观测问题,也可应用于对大型建筑、桥梁、山体等的多维多点变形自动观测。
An auto-measurement method that can be used in arc-dam poly-distortion observation is introduced.According to the method, Laser and PSD devices are used to realize the displacement and angle measurement,and a series of measurement stations are set along an arc, so as to obtain the distortion information of each point. The calculation formulas and the technical solution are also given. The method can also be used in other distortion-measurement fields, such as building, bridge and mountain distortion-measurement.
