BIM-based highway tunnel design method

Abstract

The invention discloses a BIM-based highway tunnel design method. 1: Establish terrain and geological models according to surveying and survey data, and determine the tunnel surrounding rock level; 2: Define a tunnel material feature library, and establish a tunnel cross-section template library according to the calculation; 3: According to the overall design plan of the project, establish the three-dimensional route of the tunnel, the space curve model of the transverse passage and the inclined shaft; 4: According to the design mileage of each cross-section of the tunnel, establish the segmental model of the main tunnel of the tunnel; 5: Establish the inclined shaft, the transverse passage, and the tunnel Door structure model; 6: Establishment of other auxiliary engineering measures components of the tunnel, steel bars, steel supports, steel frames, electromechanical components; 7: Statistics of the tunnel engineering quantity, application of BIM model. The invention integrates the terrain and geological models with the main body of the tunnel, and can modify the three-dimensional lines in real time and automatically modify the associated drawings, so as to achieve the purpose of complete expression of engineering design information in the BIM model, and provide assistance for later model information transmission and application.

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
