Detailed Description
The present invention is further described in detail with reference to the drawings and specific embodiments in the specification, and the operation steps of the following embodiments are all implemented based on a MicroStation platform.
As shown in fig. 1, an embodiment of the present invention provides a method for modeling building information between metro areas, including the following steps:
s101, ultrahigh parametric modeling is carried out to obtain an ultrahigh orbit model, wherein the ultrahigh parametric modeling comprises the following steps: obtaining an ultrahigh orbit model according to the type of the three-dimensional space route segment and the ultrahigh value of the three-dimensional space route segment;
specifically, different track models are established according to actual terrain conditions during subway track modeling, the track models mainly include a straight-line section track model, a straight-slow section track model, a circular curve section track model, a straight-line section track model and the like, and the different track models correspond to different ultrahigh values. The superelevation means that when a train runs on a non-linear track route, a sideslip is generated by a lateral force or a centrifugal force, and the sideslip causes abrasion between train wheels and rails, so that in order to allow the train to smoothly and safely pass through the non-linear section, a cross slope with an outer side higher than an inner side is provided on the cross section of the section, and the cross slope is superelevation. And the ultrahigh parametric modeling is mainly used for obtaining a corresponding ultrahigh track model by adopting the existing data modeling technology according to the type of the three-dimensional space route segment and the ultrahigh value corresponding to the three-dimensional space route segment.
S102, modeling the subway interval component to obtain a subway interval component model, wherein the subway interval component model comprises the following steps: a linear continuous member model and a discontinuous member model;
specifically, the purpose of modeling the subway interval component is to obtain a subway interval component model, and the subway interval component model exists to be combined to an ultrahigh rail model to form a subway interval tunnel model. The metro section component model can be divided into a linear continuous component model and a discontinuous component model according to a modeling mode.
The linear continuity member model mainly comprises a viaduct model, a track bed model, a steel rail model and the like, wherein the model is a section of continuous model and is obtained by stretching a stretching tool in a subway interval modeling tool developed based on pure MDL language of a MicroStation platform.
The discontinuous member model mainly comprises a sleeper, a sound barrier, a contact rail bracket, a connecting terminal, a fastener, a sleeper and the like, the model is a single independent model, the model can be built according to a construction drawing by using revit software and then stored in a computer file folder in a model family mode, and the discontinuous member model can be directly called when the subway interval tunnel model is built.
S103, combining the subway interval component model to the ultrahigh rail model to form a subway interval tunnel model;
after the ultrahigh rail model is built, the subway interval component model is combined to the ultrahigh rail model according to the actual terrain condition to form a complete subway interval tunnel model.
Therefore, the method can obtain the ultrahigh orbit models of different three-dimensional space route sections by only controlling the types of the three-dimensional space route sections and the ultrahigh values of the three-dimensional space route sections on the basis of the existing data modeling technology without manually participating in ultrahigh orbit modeling, and compared with the traditional manual modeling, the method has shorter modeling time and higher precision.
Further as an optional implementation manner, the method further includes a step S104 of counting the engineering quantity of the tunnel model between the subway sections;
the step S104 of counting the engineering quantity of the tunnel model between the subway sections comprises the following steps:
s1041, calling a style tool to assign styles and types to the discontinuous component model;
s1042, searching the name of the discontinuous component model to obtain a project amount statistical table of the discontinuous component model method.
After the subway interval tunnel model is established, the engineering quantity of the subway interval component model needs to be counted for facilitating model delivery.
The traditional engineering quantity statistical method is to extract engineering quantity by using BIM software, the statistical content mainly includes the quantity, length, volume surface area and the like of a certain model, and in the engineering quantity statistical process, a pattern and a category need to be defined and added to a model object, and an engineering quantity output rule also needs to be defined.
The method comprises the steps of establishing a subway interval component model style type through an item under the style type of a subway interval modeling tool developed based on a MicroStation platform, then selecting style names such as basic definitions in style and type views respectively, and endowing the style and the type to a corresponding subway interval component model through the style tool under the subway interval modeling tool. According to the method, the name of the metro interval component model is retrieved, the engineering quantity information of the metro interval component model is directly obtained, compared with a traditional engineering quantity statistical method, the method saves a middle complex operation process, and has the advantages of being convenient to operate, simple and fast.
As a further optional implementation manner, the step S101 of obtaining the ultra-high orbit model by the ultra-high parametric modeling includes the following steps:
s1011, segmenting the three-dimensional space route;
s1012, determining the type of the three-dimensional space route segment;
s1013, obtaining the ultrahigh value of the three-dimensional space route segment according to the determined type;
and S1014, obtaining the ultrahigh track model according to the type and the ultrahigh value of the three-dimensional space route segment.
Specifically, a three-dimensional space route can be segmented by using a flat curve element, wherein the flat curve element refers to the geometric form and parameters of a road plane curve, such as a circular curve radius, a relaxation curve parameter, a curve length, a tangent length, an outer radius and the like, the three-dimensional space route is segmented according to the flat curve element, the types of the obtained three-dimensional space route segments include a straight line segment, a straight-slow segment, a circular curve segment, a slow-slow straight segment and the like, different types of three-dimensional space route segments correspond to different ultrahigh values, and the creation of ultrahigh track models of different segments can be completed by adopting the conventional data modeling technology according to the types and the corresponding ultrahigh values of the three-dimensional space route segments.
Optionally, the different segmented superelevation track models can be combined arbitrarily to form a complete superelevation track model according to actual needs.
As a further alternative implementation, the step S1013 of obtaining the superelevation value of the three-dimensional route segment according to the determined type includes the following steps:
s10131, if the determined type is a straight line segment, the ultrahigh value of the three-dimensional space route segment is 0;
s10132, if the determined type is a straight and slow section, continuously changing the ultrahigh value of the three-dimensional space route section from 0 to a first set value;
s10133, if the determined type is a circular curve section, the ultrahigh value of the three-dimensional space route section is a second set value;
and S10134, if the determined type is a slow straight section, continuously changing the ultrahigh value of the three-dimensional space route section from a third set value to 0.
Specifically, when the route segment is a straight line segment, the train does not receive a centrifugal force or a lateral force, and the route does not need to be set to be ultra-high, so that the ultra-high value of the straight line segment is set to 0.
When the route is a straight and slow section, namely the route is gradually changed from a straight section to a gentle route section, when the train enters the straight and slow section route, the centrifugal force or the transverse force applied to the train is gradually increased, so that in order to counteract the gradually increased centrifugal force, the ultrahigh value of the straight and slow section route is also continuously changed from 0 to the first set value.
When the route is a circular curve section, the circular curve section is used as a part of the circumference, the curvature of the circular curve section is not changed, the magnitude of the centrifugal force or the transverse force applied to the train is a fixed value, and therefore the ultrahigh value of the circular curve section is also a fixed value and can be set as a second set value. The second setting value can be flexibly set according to the actual terrain condition, for example, when the radius of the circular curve section is larger, the second setting value can be adjusted to be larger, and when the radius of the circular curve section is smaller, the second setting value can be adjusted to be smaller.
When the route is a gentle straight section, namely the route is gradually changed into a straight section from the gentle route section, the centrifugal force or the transverse force applied to the train is gradually reduced until the centrifugal force or the transverse force disappears, and therefore the ultrahigh value of the train is continuously changed to 0 from the third set value.
As shown in fig. 2, taking creating a straight-line segment, a straight-slow segment, a circular curve segment and a slow straight-line segment ultrahigh track model as an example, when the determined three-dimensional spatial route type is the straight-line segment, the ultrahigh value of the straight-line segment is 0, and the rotation mode of metro interval component models such as a steel rail, a sleeper and a track bed does not need to be processed, so that the straight-line segment ultrahigh track model can be directly generated; when the type of the determined three-dimensional space route is a straight and gentle section, firstly, inputting a first set value on an interactive interface developed on the basis of a MicroStation platform, enabling the ultrahigh value of the straight and gentle section to be continuously changed from 0 to the first set value, then, setting the turning direction of the straight and gentle section, enabling subway interval component models such as a steel rail, a sleeper and a track bed to rotate according to the linear gradual change mode of the straight and gentle section route, and further generating a straight and gentle section ultrahigh track model according to the mode; when the determined three-dimensional space route type is a circular curve section, setting an ultrahigh value (namely a second set value) and ultrahigh steering to generate a circular curve section ultrahigh track model; when the determined three-dimensional space route type is a straight section, the generation process is similar to a straight section and slow section ultrahigh track model, but the ultrahigh value is continuously changed to 0 from a third set value.
The method can be divided into two types, namely a linear continuous component model and a discontinuous component model according to the classification of the subway interval component model, and two implementation schemes for combining the subway interval component model to the ultrahigh rail model correspondingly exist, namely: the linear continuous member models are combined onto the superelevation track model and the discontinuous member models are combined onto the superelevation track model. However, in the modeling process, the metro section component model required by a certain section of ultrahigh track model may be only a linear continuous component model or only a discontinuous component model or both the two metro section component models, so that the combination of the metro section component model to the certain section of ultrahigh track model needs to refer to the actual modeling condition, and the certain section of ultrahigh track model refers to any one of a straight line section, a straight-slow section, a circular curve section and a slow straight section of ultrahigh track model. For convenience of explanation, the following embodiments are specifically applicable to a case where only one type of metro section component model is combined to the ultra-high track model, and two types of metro section component models are combined to the ultra-high track model at the same time.
For the second embodiment of step S103, a linear continuous member model is combined to the superelevation track model, including the following steps:
s1031, drawing a stretching route by using elements of a flat curve and a vertical curve;
s1032, picking up a point on the section of the linear continuous component model as a positioning base point, and determining the spatial position of the section of the linear continuous component model on the stretching route by using the positioning base point;
s1033, stretching the cross section of the linear continuous component model along the stretching route direction according to the determined space position to complete creation of the linear continuous component model of the ultrahigh orbit model;
s1034, automatically positioning the mileage stake marks of the linear continuous component model;
specifically, the stretching route can be accurately drawn by using a flat curve element and a vertical curve element by using PowerCivil software of Bentley company, and then the drawn flat curve and vertical curve are synthesized into a three-dimensional space curve, namely the creation of the stretching route is completed.
The cross section of the linear continuous member model is drawn in advance, and one point on the cross section of the linear continuous member model is taken as a positioning base point which is coincident with the central point of the line of the stretching line, so that the spatial position of the cross section of the linear continuous member model on the stretching line can be determined through the positioning base point.
And stretching the cross section of the linear continuous member model along the stretching route direction to complete the creation of the linear continuous member model.
As shown in fig. 3, taking the combination of the viaduct model to the straight-line segment superelevation track model as an example, a point is picked up on the cross section of the viaduct model by DP operation as a positioning base point, where XYZ in the figure is the spatial coordinate of the positioning base point; the positioning base point is coincident with the central point of the stretching route, so that the position of the cross section of the viaduct model on the stretching route can be determined. Reading the cross section of the viaduct model into a stretching tool by means of Create profile operation; and then stretching the cross section of the viaduct model along a stretching route by using the Loft operation, thus completing the creation of the viaduct model of the superelevation track model.
Further as an optional implementation manner of the first embodiment of step S103, the step S1034 of automatically locating the milepost number of the linear continuous member model is specifically:
and automatically calculating the pile number to be marked of the linear continuous component model by using the input starting pile number and the set fixed distance.
Specifically, a start pile number is input in a pile number marking tool under a subway section tool to determine a starting point of a linear continuous component model, a position of a first pile number is determined at a set fixed distance from the starting point, and a position of a second pile number is determined at a set fixed distance according to the position of the first pile number \8230, and so on, the position of the next pile number can be determined.
For the second embodiment of step S103, the discontinuous member model is combined to the superelevation track model, and the method includes the following steps:
s1035, selecting names of discontinuous component models placed on the ultrahigh rail model;
s1036, inputting pile number intervals and horizontal deviation;
s1037, placing discontinuous component models at intervals and in horizontal offset along the route direction according to the input pile numbers;
further as an alternative to the second embodiment of step S103, the step S1037 of placing the discontinuous component models at intervals of the input pile numbers and with horizontal offset along the route direction includes the steps of:
s10371, inputting a horizontal offset to determine a distance from the discontinuous member model to the route center line;
s10372, inputting pile number intervals to determine the distance between every two discontinuous component models;
s10373, determining the placement position of the discontinuous component model along the route direction according to the input pile number interval and the horizontal offset, and placing the discontinuous component model along the route direction according to the determined placement position.
Specifically, as shown in fig. 4, taking the combination of the conductor rail insulation support model to the straight-line section ultrahigh-orbit model as an example, the name of the placed discontinuous component model (unit name: conductor rail insulation support) is selected first, and the interval of the input stake numbers is 0.6, that is, one conductor rail insulation support model is placed at intervals of 0.6 stake numbers. The horizontal deviation refers to the distance from the central line of the route to the original point of the model of the discontinuous component, and specifically, two methods for setting the original point of the model of the discontinuous component are provided: the original point of the contact rail insulation support model can be arranged on the contact rail insulation support model, and the distance from the contact rail insulation support model to the central line of the route can be adjusted by adjusting the numerical value of horizontal deviation; the original point of the contact rail insulation support model can be arranged on the central line of the route, a fixed distance exists between the contact rail insulation support model and the original point of the contact rail insulation support model, the fixed distance is the distance from the contact rail insulation support to the central line of the subway route in the actual railway, and the horizontal deviation is set to be 0. Compared with the former method for setting the origin of the discontinuous component model, which needs to input specific numerical values of various discontinuous component models to the central line of the route, the latter method for setting the origin of the discontinuous component model does not need to remember the distance from the origin of the discontinuous component model to the central line of the route, and directly sets the horizontal deviation value as 0, so that the operation is simpler and more convenient. Therefore, in the present embodiment, the latter discontinuous member model origin setting method is adopted to determine the origin of the insulating support of the contact rail.
And placing a first contact rail insulation support model on the ultrahigh rail model, determining the positions of the rest contact rail insulation support models on the ultrahigh rail model according to the input pile number intervals and horizontal offset, and sequentially placing the contact rail insulation support models along the route direction to complete the operation of combining the contact rail insulation support models on the ultrahigh rail model.
