Abstract
Taking the long-distance headrace tunnel of Contract CII of the Chuosjia Hydropower Project as a case study,this paper elaborates in detail on the layout of a high-precision primary surface control network u-sing the Global Navigation Satellite System(GNSS),the role of total stations of class 1 in providing high-preci-sion angular and distance survey,as well as key survey aspects for long-distance tunnels such as regular multi-point deformation monitoring,data analysis and correction techniques for multi-point management and control.The application of these key technologies ensures precise breakthrough of long-distance water diversion tunnels and provides technical references for tunnels of the same type.关键词
