Highway tunnel designing method based on BIM

Abstract

The invention discloses a highway tunnel designing method based on BIM. The highway tunnel designing method based on the BIM includes the steps that 1, according to mapping and reconnaissance data, aterrain model and a geologic model are built, and tunnel surrounding rock grades are determined; 2, a tunnel texture feature library is defined, and a tunnel cross section model library is establishedthrough calculation; 3, according to a project overall design scheme, a tunnel three-dimensional path and cross aisle and inclined shaft space curve model is built; 4, according to design kilometersof all tunnel cross sections, a tunnel main cave subsection model is built; 5, an inclined shaft model, a cross-aisle model and a tunnel portal structure model are built; 6, other tunnel auxiliary engineering measure components including reinforcing steel bars, steel shotcrete, steel frames and electromechanical parts are built; 7, tunneling work amount accounting is conducted, and a BIM model isapplied. According to the highway tunnel designing method based on the BIM, the terrain model and the geologic model are fused with a tunnel main body, three-dimensional paths can be modified in realtime, related drawings are automatically modified, therefore, the purpose is achieved that engineering design information is completely reflected in the BIM model, and model information transfer and application in the later period are facilitated.

Description

technical field [0001] The invention relates to a highway tunnel design method, in particular to a BIM-based highway tunnel design method. Background technique [0002] BIM (Building Information Modeling; English abbreviation of Building Information Modeling) technology is developing rapidly, gradually extending from the civil construction industry to municipal engineering, rail transit, highways, railways, water transport ports and other infrastructure construction fields, making BIM also from the design stage to the The later stage of operation and maintenance developed rapidly. [0003] Compared with the construction industry, the formulation of 3D design software and standard specifications in the highway infrastructure industry lags behind, and the application of BIM in highway tunnel design is even less. This is because the design of highway tunnels is a highly complex task, which is constrained by many external conditions while considering the design efficiency. The...

Problems solved by technology

Therefore, applying the BIM three-dimensional design method to the design of highway tunnels can display and quickly solve the constraints that may affect the project in the future; from the perspective of the construction party and the owner, the designer provides accurate and easy-to-use three-dimensional The model can solve many management problems existing in the current highway tunnel construction, and can also avoid the economic loss caused by the lack of traditional two-dimensional construction drawing information, but it has not been reported yet
