BIM three-dimensional visualization deep foundation pit deformation prediction system based on genetic algorithm

Abstract

The invention provides a BIM three-dimensional visualization deep foundation pit deformation prediction system based on a genetic algorithm. The BIM three-dimensional visualization deep foundation pitdeformation prediction system comprises a field data acquisition module, a data processing prediction analysis module and a visualization module. The field data acquisition module acquires horizontaloffset of each measured direction of a deep foundation pit and stores the horizontal offset as deep foundation pit deformation monitoring data; the data processing prediction analysis module processes the deep foundation pit deformation monitoring data through a genetic algorithm, deep foundation pit deformation trend data are obtained through fitting, and the deep foundation pit deformation trend data comprises a probability and time for each measured direction of the deep foundation pit to reach a deformation limit threshold value; a data interface of the three-dimensional visualization module manages a BIM model of the deep foundation pit; and a BIM database comprises the deep foundation pit deformation monitoring data and the deep foundation pit deformation trend data so that the BIMmodel visually displays a current state and a prediction state of the deep foundation pit. In the invention, real-time acquisition, summarization, analysis and prediction of field monitoring data arerealized, predictability in a foundation pit construction process is greatly improved, and a risk occurrence probability is reduced.
