Embodiment Construction

[0030] The present invention will be described in detail below in combination with specific embodiments.

[0031] The present invention relates to a method for drawing a cross-section of an urban cut-and-cut tunnel based on ObjectARX, such as figure 1 The following steps are shown:

[0032] a. Start the user interface for drawing sections in AutoCAD: input commands in the AutoCAD command line area to display the main interface of the developed urban cut-and-cut tunnel section design module; figure 2 User interface diagram;

[0033] b. Select the type of cross-section to be drawn: from the provided separated U-shaped groove, integral U-shaped groove, one box with single hole rectangle, one box with single hole folded plate arch, one box with two holes rectangle, one box with two holes folded Choose one of the six common section types and custom types of urban cut-and-cut tunnels that need to be drawn;

[0034] c. Input tunnel section design parameters: input section height,...

Abstract

The invention relates to an urban open cut tunnel cross section drawing method based on ObjectARX. The method comprises the steps of starting a user operation interface for drawing a cross section in AutoCAD; selecting a cross section type to be drawn; inputting tunnel cross section design parameters; calling a calculation engine to calculate cross section feature point coordinate values; judging the validity of the parameters; initializing a drawing environment; automatically drawing a cross section graph in the current drawing and calculating engineering data of the cross section area; and outputting the operation log. The method provided by the invention has the characteristics of high parameterization degree and high drawing speed, and can effectively alleviate the problems of low efficiency, high error rate and time and labor consumption of reworking during design change of traditional engineering technicians in manual drawing of the cross section graph. The method is mainly applied to underground engineering such as urban open-cut tunnels, and is particularly suitable for tunnel engineering design of urban open-cut method construction.

Description

technical field [0001] The invention relates to the technical field of urban tunnel engineering design, in particular to an ObjectARX-based method for drawing a cross-section of an urban open-cut tunnel. Background technique [0002] In recent years, with the continuous development of the urban economy and the increasing population density, the urban traffic volume has increased year by year. The construction of large-scale overpasses and viaducts in the past has gradually failed to meet people's travel needs. As an efficient means of transportation, urban tunnels are gradually Construction began in large and medium-sized cities in China. [0003] According to different excavation methods, urban tunnels can be divided into open-cut tunnels and underground tunnels. Among them, open-cut tunnels are mainly suitable for areas with shallow tunnel burial depths, and are widely used in urban underground engineering. In the process of tunnel engineering construction, it is often n...
