BIM-based urban rail transit vehicle depot road deceleration strip design method

Abstract

The invention discloses a BIM-based urban rail transit vehicle depot road deceleration strip design method. The method comprises the following steps: constructing a vehicle depot road BIM three-dimensional model; constructing a whole-engineering deceleration strip work point skeleton by utilizing the road center line space line position in the vehicle depot road three-dimensional model and the road mileage information of the position of the deceleration strip stored in the table; constructing a deceleration strip segment framework according to a whole-engineering deceleration strip work point framework; constructing a deceleration strip segment main body structure three-dimensional model and a deceleration strip segment three-dimensional skeleton coordinate system; and constructing a deceleration strip segment skeleton in the constructed three-dimensional model and coordinate system of the main body structure of the deceleration strip segment, and generating all road deceleration strip BIM models of a project. The method is combined with the road BIM model design, the spatial line position of the road center line is taken as the basis, and the speed bump position information and the section size information stored in the table are utilized, so that the construction of the speed bump BIM model parameterization in the whole engineering range is realized, and the design means of the road speed bump is improved.

Description

technical field [0001] The present invention relates to the field of rail transit design, in particular to a BIM-based design method for road deceleration strips in depots of urban rail transit. Background technique [0002] Building Information Modeling (Building Information Modeling) is a new tool for architecture, engineering and civil engineering, referred to as BIM, which is used to describe computer-aided design that is mainly based on three-dimensional graphics, object-oriented, and related to architecture. The core of BIM is to establish a virtual three-dimensional model of architectural engineering and use digital technology to provide a complete architectural engineering information library for this model that is consistent with the actual situation. [0003] Carrying out the deceleration belt design of urban rail transit depot road based on BIM technology is the need of deepening depot road design. In the traditional depot road design process, the design of road ...
