Problems solved by technology

So far, there have been many achievements in large-scale geological 3D mapping in foreign countries. Domestic universities have taken the lead in starting national strategic level geological 3D modeling. The accuracy of the modeling is a large-scale model of the kilometer level. There are very few cases where geological modeling of this level of precision is applied to actual construction guidance

Abstract

The invention discloses a stratum digital twin modeling method and system based on a multi-platform structure, and the method comprises the steps: building a preliminary geological model on a GIM modeling platform through geological survey data and a design scheme at the initial stage of construction, building a preliminary tunnel model on a BIM modeling platform, and setting model monitoring points; performing model integration to obtain an integrated GIM + BIM model, and uploading the integrated GIM + BIM model to a network platform; arranging a monitoring system corresponding to the model monitoring points, establishing a monitoring database, and hooking a network platform; in construction, correcting the integrated GIM + BIM model through advanced geological prediction before excavation; and after the tunnel is excavated and the stratum is exposed, determining the actual stratum situation surrounding the tunnel, correcting the GIM + BIM model again, and pre-judging the stratum situation of the next excavation section. Multi-platform integration of forming a three-dimensional geologic model, a structure monitoring model and a monitoring data database at a network end is realized, and a GIM + BIM data comprehensive platform concept is provided.

Description

technical field [0001] The invention relates to BIM technology, in particular to a method and system for digital twin modeling of strata based on a multi-platform structure. Background technique [0002] BIM is Building Information Modeling (Building Information Modeling), as a complete information carrier of construction projects, it is an innovative design, construction and management method. BIM is a three-dimensional "visualization" digital model based on three-dimensional digital design and engineering software realized by advanced computer technology. BIM has become an important technical means for the whole process management of projects in the construction field. Currently, it is mostly used in the construction of industrial squares in the field of coal mines. [0003] GIM (Geological Information Modeling, geological information modeling technology), in order to meet the needs of mining and geological resource management, establish a three-dimensional digital model ...
