Abstract

The present invention provides a method for constructing a hydrogeological BIM model of tunnel engineering. Due to the complexity of hydrogeological conditions, limitations of cognition, and limitations of visualization tools, etc., the method and technology for constructing a hydrogeological BIM model are still immature . Most of the existing BIM modeling commercial software is aimed at industries such as oil reservoirs and mines, but few are aimed at long tunnel projects, and the workload of manual interaction is relatively large, which cannot meet the needs of large-scale engineering applications. Aiming at the characteristics of tunnel engineering hydrogeological conditions, the present invention mainly includes basic data preparation, terrain surface modeling, tunnel outer contour modeling, interesting area modeling, hydrogeological interface modeling, Boolean operation forming, hydrogeological body identification and IFC Attribute deployment, on the basis of human-computer interaction, realizes the rapid construction of hydrogeological BIM models, so as to meet large-scale engineering applications.

Description

technical field [0001] The invention relates to the technical field of railway and highway engineering, in particular to a method for constructing a hydrogeological BIM model applied to tunnel engineering. Background technique [0002] In recent years, in order to relieve urban traffic pressure and make full use of land resources, a large number of tunnel projects have been used in the construction of transportation infrastructure such as subways, high-speed rails, and highways, and groundwater problems are one of the main risk factors in engineering construction. [0003] The hydrogeological BIM model is a technology that uses computer technology to combine hydrogeological information with visualization tools in a three-dimensional environment for geological research and application. The hydrogeological BIM model is of great significance in engineering route selection, collaborative design, and construction guidance. However, due to the complexity of hydrogeological condit...
