Abstract: The irregularity, diversity, complexity and large scale of the building structure of the National Speed Skating Oval bring great difficulty to the construction measurement. The research and application of dynamic high-precision measurement technology is an important foundation to realize the high-precision lap of various professions and links in the construction process. The key technology of dynamic and high-precision construction measurement in National Speed Skating Oval has solved the technical problem of the difficulty of synchronous tensioning of large-span saddle-shaped cable net under the non-uniform force. It makes a breakthrough in the key technology of precast, installation and control precision measurement of extra-large special-shaped flexible structure roof, and realizes the transformation of precision engineering measurement from “static to dynamic” and “discrete to continuous”. A new model driven method for measuring the apparent morphology of a multi-purpose high-density netted tube is developed. It solves the problem of long distance continuous floor elevation measurement with ultra-high precision in blocked or closed environment. It effectively guides the construction operation and provided a guarantee for the development of the 2022 Winter Olympic Games speed skating project.

Key words: National Speed Skating Oval, saddle-shaped single layer orthogonal cable net, glass curtain wall, making ice floe tube, cement floor paint, dynamic and high-precision construction measurement
