Lad.Beijing 100161 China) Abstract:Top-down construction method is adopted in Stockmann Nevsky Center in St.Petersburg and location and verticality of supporting lattice column are important and difficulty points of the project.In view of the lattice column has large section and rigidity authors select calibration frame method to locate the column and adjust verticality where they use reinforced concrete guide wall instead of calibrated mount.Construction design construction technology and special requirements on technology are proposed.It proves that calibration frame method has advantages of low cost convenient construction and short construction time and precision of supporting column as permanent structure can be ensured.
