Deep foundation pit steel sheet pile deformation real-time monitoring and early warning method and system
The invention discloses a deep foundation pit steel sheet pile deformation real-time monitoring and early warning method and system. The method comprises the following steps: reconstructing a three-dimensional live-action model of the deep foundation pit in real time based on unmanned aerial vehicle aerial photography and oblique photogrammetry technologies; the distance change of the deep foundation pit point cloud model in different periods is compared by using a point cloud comparison algorithm (Multiscale Model-to-Model Cloud Compatibility, M3C2) from a multi-scale model to a model, and a deep foundation pit deformation cloud picture is obtained; and the deformation amount and the deformation rate of the steel sheet pile are measured based on the deformation cloud picture, and the deformation trend of the steel sheet pile is predicted, so that real-time monitoring and alarming of deformation of the deep foundation pit steel sheet pile are realized. The method has the effect of improving the construction monitoring quality and the engineering management level.
