ABSTRACT
In traditional construction process of huge steel structure, plane and altitude cannot be monitored at the same time, so they fail to reflect the three dimensional information of steel structures and the features of overall deformation. In order to solve this problem, we employ the three-dimensional laser scanning technology to collect three dimensional spatial data of this super-huge and profiled steel structure. On basis of these data, we reconstruct the three dimensional feature data of the structure elements from point?cylindrical?spherical and so on ,and then we can analysis the structure deformation by statistical charts. Firstly, this study put forward the remote sensing technology on overall structure of the construction process of super-huge profiled steel structure. Secondly, the stress situation, strain situation and overall deformation characteristics were also be studied with FEA simulation and LIDAR. Consequently, technical support for the process of installation, construction and the quality testing are proposed. Several typical cases of super-huge and profiled steel structure are listed to verify this method is efficient and feasible.
