摘　　要：为了查明观音岩水电站下闸蓄水后裂缝变形区发展趋势,为电站继续蓄水提供可靠变形监测数据,开展了非接触式三维变形监测试验。试验优选3套高精度三维扫描设备,直接获取变形区的三维数据,以及三维空间的线、面、体等各种试验数据。监测试验成果及时论证了裂缝变形区位移呈先快后慢,逐渐收敛的趋势,为电站继续蓄水提供了可靠依据,亦为类似工程三维监测提供了实例参考。In order to find out the development trend of fracture deformation area after the water storage of Guanyinyan Hydropower Station and provide reliable deformation monitoring data for the continuous water storage of station, the non-contact three-dimensional deformation monitoring experiments are carried out. Three sets of high-precision three-dimensional scanning equipment are used in experiments to obtain three-dimensional data of deformation zone directly, as well as the line, surface and volume data of three-dimensional space. The results of monitoring and testing show that the displacement of fracture deformation zone is fast at first and then slows down to converge gradually. The experiment data provides a reliable basis for the water storage of power station and an example reference for similar 3D monitoring.
