AUTOMATIC MONITORING OF DAM DEFORMATION BY LASER VACUUM COLLIMATION

  • 摘要: 针对大坝变形观测要求精度高和长期稳定可靠的难题，对美国斯坦福大学安装、调整直线加速器的真空中激光三点法作了关键性改进，并移用于大坝，其中用小孔代替透镜组，其作用是定位、限漂、扩束和点化.20年来，该技术已先后运用和推广到太平哨、丰满、龚嘴、桓仁、云峰和太平湾大坝，特别在丰满发挥了重大的社会效益.该技术已正式被确定用于三峡.
    Abstract: Facing the demands of high accuracy and long time stability and credibility for dam deformation monitoring,we have made certain key improvements to a laser three-point method in a vacuum line which has been used on the linear accelerator at Stanford University and then applied it to dam monitoring.The focusing lens system has been replaced by a diaphragm which can effect position location,drift limiting,beam expansion and point conversion.In the past twenty years,this technology has been applied to dams at Taipingshao,Fengman,Gongzui,Huanren,Yunfeng and Taipingwan.Great social benefits have been obtained in particular on the Fengman dam.This technology has also been chosen for the Three Gorges Dam.
