Abstract

The invention relates to an OBM-based road tunnel design method. The purposes are effectively achieved that the operation is convenient, the design precision and the modeling efficiency are improved,the size of a generated three-dimensional model is small, and the demands for splitting and data sorting of a later construction model are easily met. A tunnel three-dimensional terrain, a three-dimensional geological model are created, and tunnel surrounding rock division is conducted; a tunnel three-dimensional route model is established according to route design data; a tunnel cross section isdesigned, and a tunnel cross section template library is created; layout span lines are utilized for arrangement of surrounding rock pile numbers of a tunnel, and tunnel main hole, transverse channeland inclined well models are established; tunnel portal, portal side slope protector, steel bar, steel frame and tunnel anchor rod models are established; tunnel electromechanical, fire fighting, inner and outer prevention drainage and traffic engineering models are established; the transverse channel and main hole models are subjected to trimming modeling, a transverse channel is subjected to portal forming modeling in a main hole structure, the vehicle-passing transverse channel is subjected to sinking cable groove treatment, tunnel emergency stop widening modeling is conducted, and the tunnel model and the geological model are combined for modeling; the tunnel model is split, and tunnel components are coded.

Description

technical field [0001] The present invention relates to road tunnel BIM (building information model; English abbreviation of Building Information Modeling) technical information, especially a kind of road tunnel design method based on OBM (bridge three-dimensional modeling software; English abbreviation of OpenBridge Modeler). Background technique [0002] In recent years, the construction management of highway engineering projects tends to be refined and informatized, which can not only bring benefits, but also promote the technological development of the industry. The application of BIM technology in road tunnel engineering will produce positive effects from the early design end to construction management, and then to the operation and maintenance management of road tunnels in the later stage of the project. Therefore, the requirements for tunnel BIM technology in the design stage are getting higher and higher. [0003] In related technologies, traditional road tunnels are...
