Modeling method for shield tunnel

Abstract

The invention relates to a modeling method for a shield tunnel. The method comprises the following steps of: S1, building a parameterized family corresponding to each component contained in the shieldtunnel in Autodesk Revit software according to a design drawing, and forming a parameterized family database of the components of the shield tunnel, S2, calculating three-dimensional space position coordinates corresponding to each component of the shield tunnel to form a three-dimensional space position database, S3, synthesizing the three-dimensional space position database and the parameterized family database into a shield tunnel modeling database, S4, writing a language program in Dynamo software according to the design drawing, and S5, calling a shield tunnel modeling database in Dynamosoftware to generate a parameterized shield tunnel model. The calculation defect of Autodesk Revit in building a space curve model is overcome, and the problems that in the prior art, when Autodesk Revit builds the space curve model, the calculation defect exists, the curved surface modification process is extremely unsmooth, and the efficiency is low are solved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a modeling method for a shield tunnel. Background technique [0002] With the rapid development of China's economy, the demand for subways in various cities in China is increasing, and shield construction is one of the most widely used construction methods in subway sections. However, the construction of the shield method is complex, requiring the close cooperation of construction technologies such as air pressure supply equipment, artificial point dewatering, lining segment prefabrication, transportation and measurement in the tunnel, and the surface deformation is difficult to control, resulting in high construction costs. [0003] In the prior art, Autodesk Revit is used to build the shield tunnel model according to the drawings, but Autodesk Revit has calculation defects when building the space curve model, and the process of modifying the curved surface is very stuck and...
