BIM-based building method of geotechnical engineering monitoring model

Abstract

The invention relates to a BIM-based building method of a geotechnical engineering monitoring model. The method includes the steps of firstly, collecting monitoring data; secondly, performing interpolation processing on the monitoring data obtained in the first step; thirdly, processing the data after the interpolation processing of the second step to form a three-dimensional curved-surface model; fourthly, performing analysis and risk identification on the model formed in the third step; fifthly, pushing the data after the analysis and risk identification of the fourth step to a client. The method has the advantages that various problems caused during foundation pit engineering are expressed visually, engineering technicians can feel the deformation conditions after soil stress conditions change and the variation and trend of soil along with time and space change, and engineering dangerous situations and environment geotechnical public hazard can be conveniently discovered and forecast in real time.

Description

technical field [0001] The invention relates to a method for constructing a BIM-based geotechnical engineering monitoring model. Background technique [0002] my country's geotechnical engineering monitoring began in the early 1980s, and the monitoring technical means are mainly manual operations. With the development of computer and electronic technology, monitoring methods and technical means have also been continuously improved and upgraded. On the basis of fully studying the use experience and effects of engineering monitoring instruments, instrument types and technical performance, and quality evaluation standards, the engineering community has confirmed a batch of available instruments; the technical indicators, applicable conditions, and stability of these instruments There are also evaluation standards. Standardization, proceduralization and quality control measures for the installation, embedding and observation of monitoring instruments have also been gradually f...

Problems solved by technology

The existing foundation pit monitoring system mainly has the following disadvantages: (1) The information management function is weak, and desktop databases such as Access are generally used, which is not suitable for managing a large amount of monitoring data in multimedia forms such as text, sound, pictures and videos ; (2) The graphic visualization function is poor. Most systems only support the display of static monitoring layout diagrams, and cannot edit graphics, let alone realize the two-way linkage query between attribute data and graphic objects; (3) The query function is poor, there is no Or it only provides a very simple query function, and cannot perform complex combined queries; (4) the function is relatively single

[0006] To sum up, the current geotechnical engineering monitoring report still stays in the traditional file management mode based on two-dimensional charts, there is no monitoring graphic database, and the data cannot be shared

This application mode not only greatly reduces the monitoring function, work efficiency and management analysis level, but also fails to bring into play the potential value of massive monitoring data.
