The present invention is described in detail below with reference to examples, but the present invention is not limited to these examples.
The embodiment of the invention provides a diversion tunnel parameterized design method based on a building information model, which comprises the following steps of:
s1, creating a plurality of structure general models according to general structural types of structures at two ends of a diversion tunnel;
s2, creating a hole line framework 2 of the diversion tunnel to be modeled according to the design requirement of the diversion tunnel to be modeled, and creating a tunnel model 7 and a plurality of structure positioning marks 3 on the hole line framework 2;
s3, according to the plurality of structure positioning marks 3, calling the plurality of structure general models to a hole line framework of the established hole body model, and adjusting according to design requirements to obtain the diversion tunnel model.
In this embodiment, the diversion tunnel model in S3 is adjusted according to the design requirement, which may specifically be:

In this embodiment, the modeled diversion tunnel model is shown in fig. 8, and includes a tunnel model 7, a water inlet channel model 8, a blocking tower model 9 and a water outlet model 10.
The building information model (Building Information Modeling, abbreviated as BIM) is used as an important technical means for improving the design quality and the design efficiency, and is applied to the engineering field. The method of the present invention may be implemented based on BIM.
Therefore, in this embodiment, the S1 may specifically be:
and creating a plurality of structure universal models in the building information model software according to the universal structural types of structures at the two ends of the diversion tunnel.
In particular, the building information model software may be CATIA software.
Specifically, the diversion tunnel is generally composed of structures such as a water inlet channel, a plugging tower, a tunnel body and a water outlet, the middle part of the diversion tunnel is the tunnel body, one end of the tunnel body is communicated with the water inlet channel through the plugging tower, and the other end of the tunnel body is communicated with the water outlet. In practice, the trend and the structure of the tunnel body need to be determined according to factors such as actual terrain, geological conditions and the like of the engineering, so that the structural types of the diversion tunnel body have larger differences in different engineering or different sections in the same engineering; the structures at the two ends of the tunnel body are mostly in a general structural form, and the dimension adjustment is generally carried out by combining engineering practice on the basis of the general structural form during design, so that the difference of the structures at the two ends of the tunnel body in different engineering is small. Therefore, structures at both ends of the shaft have the possibility of parameterized mass design.
Based on the above, in this embodiment, according to the general structural form of the structures at the two ends of the diversion tunnel, a plurality of general models of the structures are created, so as to implement parameterized design of the diversion tunnel.
In practice, the structures such as the water inlet channel, the plugging tower, the water outlet and the like can have various general structural forms, and correspondingly, the general model of each structure can also have a plurality of structures. The present embodiment establishes a structure common model library that contains a plurality of common models of a plurality of structures.
Specifically, the plurality of structure common models in the present embodiment includes at least one water inlet channel common model 4, at least one plugging tower common model 5, and at least one water outlet common model 6.
In this embodiment, in S2, according to the design requirement of the diversion tunnel to be modeled, the hole line skeleton 2 of the diversion tunnel to be modeled is created, which may specifically be:
according to the design requirement of the diversion tunnel to be modeled, an initial plane hole line 1 of the diversion tunnel to be modeled is created;
and adjusting the initial plane hole line 1 according to the designed longitudinal slope of the diversion tunnel to be built to form a hole line framework 2.
Specifically, the longitudinal slope is designed to be the ratio of the elevation difference of the two ends of the tunnel body section on the diversion tunnel line to the horizontal projection length of the tunnel body section.
Specifically, as shown in fig. 2, in this embodiment, an initial planar hole line 1 is created according to the projection of the diversion tunnel to be modeled on a horizontal plane, and on this basis, the initial planar hole line 1 is adjusted along a vertical direction according to a designed longitudinal slope of the diversion tunnel to be modeled to form a hole line skeleton 2. In practice, the design longitudinal slope of the diversion tunnel body should be determined according to the water inlet height Cheng Geli of the diversion tunnel, the bending radius of the tunnel body should not be smaller than 5 times of the hole diameter according to the standard requirement, the corner should not be larger than 60 degrees, the straight line section should be arranged before and after the bending section, the length of the straight line section should not be smaller than 5 times of the hole diameter, and the construction of the hole line skeleton 2 should be completed by combining the standard.
In practice, the tunnel line skeleton 2 may be used as a central axis of the bottom of the tunnel body of the urban gate-type diversion tunnel.
Specifically, a plurality of structure positioning marks 3 are created on the hole line skeleton 2, and the structure positioning marks 3 are elements such as points, lines, planes and the like created on the hole line and are used for determining calling positions of structures such as a water inlet channel, a plugging tower, a water outlet and the like on the hole line.
In practice, the specific positions of structures such as a water inlet channel, a plugging tower, a water outlet and the like are reasonably determined according to engineering conditions of a water inlet and a water outlet of the diversion tunnel and comprehensively considering factors such as topography, geology, water flow conditions, construction difficulty, influence on surrounding environment and the like.
Specifically, the structure locating marks 3 are created on the initial planar hole line 1 and lie on the normal plane of the initial planar hole line 1. After the structure positioning mark 3 is created, the vertical position of the structure positioning mark 3 is adjusted according to the designed longitudinal slope, so that the initial plane hole line 1 can be adjusted, and a hole line framework 2 is formed; when the vertical position of the structure positioning mark 3 is adjusted, the final position of the hole line skeleton 2 is also determined.
In this embodiment, in S3, according to the plurality of structure positioning marks 3, the plurality of structure general models are called to the hole line skeleton of the created hole body model, which may specifically be:
and adjusting the position parameters of the plurality of general models of the structures according to the plurality of structure positioning marks 3, and calling the adjusted general models of the structures to the hole line skeleton of the established hole body model.
Specifically, each structure generic model includes an initial structure, input elements, an input condition field, and a control parameter field. The initial structure can be built in BIM software such as CATIA and the like and is used for reflecting the three-dimensional structural style of a general model of the structure, and input elements, input condition fields and control parameter fields are all associated with the initial structure.
Specifically, the input elements are points, lines, planes and other elements created or set on the initial structure, which are used for determining the spatial position and the shape of the initial structure, when the initial structure is called or adjusted, a specific input element can be designated on the initial structure as a base point of related operation, and the specific setting position of the input element can be determined in combination with design requirements. The number and positions of the input elements of the general model of each structure may be set according to actual conditions, and as illustrated in fig. 3 to 5, for example, the inlet channel input element 41 includes a point, a vertical plane, and an inlet channel axis; the plugging tower input element 51 comprises points and vertical faces; the water outlet input element 61 comprises a point, a start point vertical plane and an end point vertical plane.
In particular, an input condition field is used to associate an input element with the structure-positioning mark 3, and the input condition field may be in the form of a dialog box. In this embodiment, a dialog box for inputting a condition field is started, in which an input element on an initial structure including elements such as a point, a line, and a plane is displayed, and then a corresponding element in a structure positioning mark 3 to be associated with the input element is selected in an option field of the dialog box, so that the initial structure can be called onto the hole line skeleton 2, and the input element of the initial structure is ensured to overlap with the corresponding element on the structure positioning mark 3, thereby realizing quick and accurate call of a structure general model onto a designated position on the hole line skeleton 2.
In particular, the control parameter field is used to adjust the initial structural style and size, and the control parameter field may be in the form of a dialog box. In this embodiment, after the initial structure is called to the hole line skeleton 2, a dialog box for controlling parameter fields can be started by selecting the initial structure, and then design parameters such as a section type, a section height, a section width, a section edge length, a section slope ratio and the like of the initial structure are adjusted in the dialog box, and parameter options of the dialog box can be specifically set when the initial structure is constructed.
According to the steps, the construction of the structure design model at the two ends of the diversion tunnel is completed, and the design flow of the structure design model is shown in fig. 6.
In this embodiment, the structures at the two ends of the diversion tunnel are designed in a parameterized manner, and the tunnel body is also designed in a parameterized manner. Because the shaft portion needs to be designed in combination with engineering terrain and geological conditions, the parameterized design of the shaft differs from the way other structures build a common model.
Specifically, in this embodiment, creating the hole model 7 on the hole line skeleton 2 in S2 may be:
creating a design parameter list of the cavity model 7;
based on the list of design parameters, a cavity model 7 is created on the hole line skeleton 2.
In this embodiment, the design parameter list of the cavity model 7 is created, which may specifically be:
a list of design parameters for the cavity model 7 is created in EXCEL software.
Specifically, because the span of the tunnel body is generally longer, the topography and geological conditions of each section on the tunnel body are different, so that the tunnel body can be reasonably segmented according to the on-site condition in actual engineering, and each section is designed so that parameters such as the length of each section of the tunnel body, the tunnel size, the lining thickness and the like all meet the actual engineering requirements. According to the geological conditions, internal water pressure, surrounding rock stress, deformation conditions and other factors of the diversion tunnel body, the control parameters such as the tunnel section and the size of the tunnel body, the segmentation interval of the tunnel, the lining thickness, the control points of the tunnel body, the control section of the tunnel body and the like are determined, and a design parameter list of the tunnel body model 7 is created in EXCEL software by the control parameters.
In this embodiment, the tunnel body model 7 is created on the tunnel line skeleton 2, which may specifically be:
creating a macro file in CATIA software according to the design parameter list;
and running the macro file to generate a tunnel body model 7 on the tunnel line skeleton 2.
In the embodiment, a macro file, namely a macro language program, is created in a secondary development module in CATIA software, and the macro language program can call a design parameter list of a cavity model 7 in an external EXCEL form into the CATIA software, and the CATIA software automatically generates a cavity section control section 71 and a cavity section control point 72 on a cavity line skeleton 2 according to the design parameter list and automatically generates a cavity section sectional lining 73 to complete the creation of the cavity model 7, thereby realizing the parameterization design of the cavity and the parameterization design of the whole structure of the diversion cavity. Specifically, the operation logic of the macro file of the present embodiment is shown in fig. 9.
The foregoing description is only a few examples of the present application and is not intended to limit the present application in any way, and although the present application is disclosed in the preferred examples, it is not intended to limit the present application, and any person skilled in the art may make some changes or modifications to the disclosed technology without departing from the scope of the technical solution of the present application, and the technical solution is equivalent to the equivalent embodiments.
