Development of A Three-dimensional Modeling Method for Monitoring Overall Foundation Pit Deformation Based on Terrestrial Laser Scanning
Concrete diaphragm wall is widely used in deep foundation pit projects in city.Its lateral deformation is an important item in the deformation monitoring of the retaining structure of foundation pit.Traditional monitoring techniques for concrete diaphragm wall deformation collect data only from several sections,failing to understand the overall foundation pit deformation.Taking the north pit of Huaihai road station on Shanghai Metro Line 13 as an example,this study measures overall deformation by means of terrestrial laser scanning.Methods of data collection and data process will be introduced.A three-dimensional modeling algorithm using point cloud data of foundation pit is proposed so that the overall model of the concrete diaphragm wall can be got.And finally the overall deformation can be got by comparing the model of different periods.
