All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Example 1
The method for automatically counting and calculating the engineering quantity of the highway tunnel provided by the embodiment comprises the steps of counting and calculating the engineering quantity of linear engineering (namely counting and calculating the engineering quantity of a lining section type) and counting and calculating the engineering quantity of a node, and is shown in fig. 1 and 2. The statistical calculation process of the engineering quantity of the linear engineering comprises the following steps:
step 1: and acquiring all lining section types of the corresponding tunnel according to the BIM parameterized design result of the highway tunnel.
A BIM (building information modeling) parameterized design project of a road tunnel is created on the basis of the design of a tunnel route, lining section types under different geological conditions along the tunnel are created according to the BIM parameterized design result requirements of the road tunnel, and the lining section types needed to be used are prepared mainly according to the conditions of road grades, tunnel lengths, geological conditions, specifications, design requirements and the like, namely the lining section types in the step 1 are several lining section types to be used, and the concrete lining section types used in the road tunnel project are determined in the step 4.
Step 2: calculating the linear meter engineering quantity of each lining section type, wherein the specific calculation process comprises the following steps:
step 2.1: and taking each lining section type as a design object, and splitting the design object into a plurality of sub-objects.
The tunnel engineering quantity statistical calculation is composed of engineering quantity calculation of a plurality of design objects, and the plurality of design objects comprise the linear meter engineering quantity and the node engineering quantity of each section of lining section type. A single design object may contain multiple sub-objects, for example, a tunnel lining profile type including multiple sections of anchor, primary lining, inverted arch, arch wall, etc. In this embodiment, the engineering quantities of the object all refer to engineering quantities of different engineering quantity attributes of the object.
Because of insufficient design depth or difficult graphic representation, some design objects have no graphics, and such objects are called dummy design objects or dummy objects for short, such as tunnel secondary lining reinforcing bars at the time of initial setting. The method can be used for counting geometric modeling objects which are modeled, and counting virtual objects without geometric modeling, and is suitable for different design depth requirements and making different statistical calculation strategies.
Before parametric design, a design object is split into a plurality of sub-objects, for different projects or schemes, a parametric model and a project quantity calculation strategy of the sub-objects do not need to be edited again, or only partial attributes of the sub-objects need to be modified, reusability and sharing of each sub-object are greatly improved, and then the sub-objects are combined by using geometric and engineering relations, so that parametric design efficiency is greatly improved, and further statistical calculation efficiency is improved.
Step 2.2: and establishing a parameterized model of each sub-object in a database table structure form and defining an engineering quantity calculation strategy of each sub-object.
The parameter attribute of each sub-object and the engineering quantity attribute of the engineering calculation strategy are the core of the engineering quantity calculation of a single sub-object, the attribute can be defined in a database table structure, and the statistical calculation of the engineering quantity of the sub-object is directly involved. The parameter attribute values of the sub-objects are derived from the design parameters, the geometric figures and the attached information of the sub-objects, and a parameterized model of each sub-object is constructed in a form of a database table structure, such as the parameter attribute table structure of the sub-object shown in table 1.
TABLE 1 parameter Attribute Table Structure for sub-objects
Design parameters and geometric quantities are fixed by parametric design and geometric modeling, and are defined in table 1 for convenience of display and formula configuration, and custom variables must be strictly defined here.
PRO policy number: calculating a strategy number and an integer value associated with the attribute, numbering from 3, and reserving the first 2;

ATTR _ SYMBOL references name: symbolic expression of object names, character strings, keywords for formula analysis, need to be unique;
ATTR _ TYPE attribute value TYPE: the type of attribute value is distinguished, and the integer value has three types: 0-design parameter, 1-geometric quantity, 2-self-defined variable;

Illustratively, examples of the policy number and the belonging object type ID are shown in table 2, and examples of the attribute value type and the attribute display order are shown in table 3.
TABLE 2 policy number and belonged object type ID
TABLE 3 Attribute value types and Attribute display sequences (Table 2, corresponding to Table 2 sequence number)
As shown in table 1, the parameter attribute of the sub-object has 11 fields, where it needs to be described that:
1) the attribute value types of field 5 are divided into three types: designing parameters, geometric quantities and custom variables; design parameters and geometric quantities are extracted from the design of the sub-object (e.g., from a three-dimensional model of the sub-object), and custom variables are obtained from formula calculations or user input;
2) custom variables calculated using the formula must set the calculation formula and the appropriate calculation order, i.e., fields 9 and 10;
3) the 'reference name' of the field 3 adopts a uniform naming specification, and all parameter attributes of the sub-object can be designed through the edit box shown in FIG. 3; the naming method of the attribute of the design parameter class is generally as follows: [ object name ] [ sub-object name ]. parameter ] [ attribute name ], wherein, "[" and "]" refer to start-stop symbols, are not actually formed characters, and each field name is linked by "-"; the naming method of the geometric quantity type attribute is generally as follows: [ object name ] [ sub-object name ] [ geometric attribute name ], wherein the geometric attribute name generally has a length, an area, a volume, a surface area and the like; the general way to customize the naming of the variable attributes is: [ object name ] [ sub-object name ] [ variable name ].
The engineering quantity calculation strategy represents the engineering quantity calculation process of one sub-object and consists of 2 parts: intermediate custom variables and engineering quantity attributes. The intermediate custom variables are input variables of engineering quantity calculation, and for example, the reinforcement ratio, the soil-rock ratio, the water content and the like can be used as the intermediate custom variables of the calculation. The engineering volume attribute of each sub-object is defined in the form of a database table structure, such as the engineering volume attribute of the sub-object shown in table 4.
TABLE 4 engineering quantity attribute table structure for engineering calculation strategy of sub-object
The difference between the engineering quantity attribute and the parameter attribute is that the engineering quantity attribute is finally generated into the engineering quantity table by one key, and the parameter attribute is not the direct output content of the engineering quantity table.
PRO policy number: calculating a strategy number and an integer value associated with the attribute, numbering from 3, and reserving the first 2;

Exemplary engineering quantity attributes are shown in tables 5 and 6, and in FIG. 4.
TABLE 5 policy number, first level name, second level name, and third level name
TABLE 6 Unit, whether it is a long rice attribute, etc. (Serial number corresponding to TABLE 5, Table 5)
As shown in table 4, the engineering volume attribute has 16 fields, where it needs to be noted that:
1) the engineering quantity attribute has three levels of naming: the first-level name is an object name, the second-level name is a branch name of the object, and the third-level name is a material name, wherein the third-level name can be null and is represented by a negative sign;
2) as with the custom variables of table 1, the engineering quantity attribute calculated using the formula must set the calculation formula and the appropriate calculation order, i.e., fields 14 and 15;
3) if the engineering volume attribute defines a reference name, it may be referenced by subsequent computations, i.e., field 16.
If the parameterized model and the engineering quantity calculation strategy of a certain sub-object are constructed and defined in other tunnel projects or other lining section types, the parameterized model and the engineering quantity calculation strategy of the sub-object can be directly multiplexed or shared without being constructed again. Illustratively, when another lining section type also contains an arch wall, the parameterized model and the engineering quantity calculation strategy of the arch wall of the previous lining section type can be directly reused during the construction of the parameterized model and the definition of the engineering quantity calculation strategy, and the parameterized model and the engineering quantity calculation strategy of the sub-object existing in the previous tunnel project can be reused and shared for different tunnel projects, so that the efficiency is greatly improved, the repeated use in one configuration is realized, and the use by multiple persons is realized by one person.
The automation of the engineering quantity calculation process is realized by constructing a parameter model and defining an engineering quantity calculation strategy, the seamless connection with parametric modeling is realized, and the efficiency of the whole forward design is improved.
It should be added that a group of engineering quantity calculation strategies can be repeatedly applied to multiple instances of similar objects, the statistical calculation methods of the engineering quantities of the same class of objects are different due to different geometrical structures, multiple sets of engineering quantity calculation strategies can be defined according to specific situations for the same class of objects, and individual parameters and calculation strategies can be finely adjusted according to specific objects and specific situations, for example, adjustment of stratum porosity, permeability coefficient and the like is required when calculating the grouting quantity of advance support, adjustment of soil-rock ratio is required when calculating excavation, even a calculation formula of a specific design instance can be adjusted on the basis of a default strategy, and a proper engineering quantity calculation strategy is conveniently selected for engineering quantity calculation, for example: the open cut tunnel section lining can respectively define engineering quantity calculation strategies aiming at the conditions of a biased wall and an unbiased wall.
Different engineering quantity calculation strategies are defined according to the design depth so as to adapt to the fineness of engineering quantity calculation in different periods, and the engineering quantity statistical requirements of different design stages and different design accuracies can be met. The parameterized model and the calculation strategy in the engineering quantity calculation process are independent from the design process, and the configuration of the engineering quantity calculation strategy is completed by experienced engineering designers, so that professional and reasonable division of labor for development and configuration is realized.
The parameterized model is built in a database table structure mode, and the engineering quantity calculation strategy is defined, so that multiplexing and sharing are convenient, and design experience is digitized.
Step 2.3: and reading the parameterized model and the engineering quantity calculation strategy of each sub-object, and carrying out analysis calculation on the parameterized model and the engineering quantity calculation strategy to obtain the linear meter engineering quantity of each sub-object with different engineering quantity attributes, as shown in fig. 5.

The calculation formula is an essential component of the parameter attribute and the engineering quantity attribute of the sub-object. The calculation formula consists of a reference name, a mathematical coincidence and a numerical value of the attribute, wherein the use form of a reference variable is as follows: @ is (reference name), and is referred to in the calculation formula, as shown in fig. 6, the analytic calculation process of a calculation formula is:
step 2.3.1: acquiring a calculation formula and a reference attribute in the calculation formula;
step 2.3.2: extracting a reference attribute value from the cache according to the reference name, and replacing a corresponding character in the calculation formula with the reference attribute value;
step 2.3.3: and calculating a specific value of the calculation formula, and storing the specific value into a cache in a mode of a "< key, value >" pair, wherein the "key" is a reference name of the attribute of the current calculation, and the "value" is a calculation result.
It should be added that, in step 2.3.3, basic mathematical functions, such as trigonometric functions, power exponentials, etc., can be analyzed and calculated; also supports function expansion, such as a function of weight from the diameter of the known steel bar. The analytical calculation of the calculation formula supports the expansion of the calculation function, the basic function is difficult to realize for complex and fixed calculation in engineering, the self-defined variables are too many, and the calculation capability can be improved by the expansion of the calculation function, so that a user can edit the calculation formula conveniently.
Exemplary, analytical calculation process of calculation formula:
