The method of constructing tunnel bim model based on revit platform

Abstract

The invention discloses a method for constructing a tunnel BIM model based on a Revit platform. According to the method, a tunnel component parameterized family is constructed based on a Revit software platform. A tunnel BIM model is built, classification and summarization are carried out to form a component family library, all component families in the family library are directly called when thetunnel BIM model is built, parameterized automatic driving is achieved through an external data file, parameters of components of the same type can be rapidly adjusted to generate new components, thenew components conform to the actual engineering situation, the repeated family building process is reduced, and the modeling efficiency is greatly improved. In the modeling process, tunnel componentsare classified and coded in a unified mode, uniqueness of a component family is guaranteed, retrieval and updating are convenient, meanwhile, parameters such as sizes involved in the model construction process are designed, consistency and standardization of information expression are achieved by sharing parameter files, and therefore an accurate data basis is provided for tunnel operation and maintenance.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a method for constructing a tunnel BIM model based on a Revit platform. Background technique [0002] As one of the important transportation infrastructures, the operation and maintenance of tunnels play a decisive role in the development of the national economy. With the rapid growth of the operating mileage of tunnels in our country, the problems of tunnel operation and maintenance have become increasingly prominent. At present, the informatization and intelligence of tunnel operation and maintenance management are still in their infancy, which is far from the goal of "smart transportation". The informatization of existing tunnels is the basis for intelligent operation and maintenance. How to quickly and standardize the establishment of tunnel information models is a key issue that must be solved for intelligent operation and maintenance. [0003] Due to the influen...
