Tunnel structure open cut section parameterization design method based on BIM

Abstract

The invention relates to a BIM-based tunnel structure open cut section parameterization design method, and relates to the technical field of BIM in the engineering design industry, and the method comprises the following steps: S1, measuring data, S2, building a tunnel plane route, S3, building route vertical section parameterization analysis, S4, building a tunnel closed frame structure parameterization cross section, and S5, building a tunnel open cut section closed frame model. The method has the beneficial effects that the parameterized design of the open cut section of the tunnel is realized through the parameterized model of the BIM technology, in the method, intermediate links do not need to be considered in the design process through parameterized deconstruction of different data and establishment of a parameterized driving relation, and the design efficiency is improved. According to the method, the finally output drawings and engineering quantities come from the input of the model and the original driving parameters, for design optimization and change, the accuracy and consistency of design results can be ensured while the design efficiency is ensured, and in the method, the output design results and the input design change are synchronized in real time, so that the requirements during use are met.

Description

technical field [0001] The invention relates to the BIM technical field of the engineering design industry, in particular to a BIM-based parametric design method for an open-cut section of a tunnel structure. Background technique [0002] BIM is the abbreviation of Building Information Model. Based on three-dimensional digital technology, it integrates the engineering data model of various related information of construction projects. It provides a new engineering design process concept parametric change technology that will help designers more effectively shorten design time, improve design quality, and improve responsiveness to customers and collaborators. Collaborative design greatly improves the mutual communication between design disciplines, avoids the incompleteness and uncertainty of design data caused by physical transmission, improves design quality and improves design efficiency. BIM technology allows designers to make any desired modifications at any time, anywh...

Problems solved by technology

[0003] In the past ten years, BIM technology has developed rapidly in China, especially in the field of construction. There are many mature application tools and systems on the market, and there are also industry standard policies, but the application in tunnel engineering is relatively weak and there is no targeted Technical tools are available, but there are no good practical cases to refer to. Tunnel engineering is different from construction engineering. The tunnel itself is mostly a space curve. The existing single technical tools and methods cannot meet the requirements of tunnel plane, longitudinal section, and transverse section. Parameter Driven Design Work

[0004] At present, the engineering modeling of the closed frame structure of the domestic tunnel cut-and-cut section is mostly manual modeling, which cannot deal with the changeable cross-section types, the efficiency is low, and the accuracy of manual modeling is low. Patents related to BIM design have been published

For example, the Chinese patent application number CN201810817826.5 discloses a BIM-based method for designing the excavation surface of the foundation pit of the open-cut section of the tunnel, which mainly solves the application of the excavation of the tunnel foundation pit. It is not involved, so it is necessary to design a BIM-based parametric design method for the open-cut section of the tunnel structure to solve the above-mentioned problems
