Examples
The method for establishing the parametric model of the faceplate dam toe board by utilizing the CATIA three-dimensional software realizes the parametric modeling process of the faceplate dam toe board under the CATIA three-dimensional software environment, and comprises the following specific implementation processes:
the method comprises the following steps: and creating a three-dimensional model skeleton of the panel dam. The three-dimensional model skeleton of the face plate dam comprises a dam coordinate system 1, a dam axis 2, a river-oriented axis 3, a dam top elevation surface 4, a dam body face plate sketch 5, a toe plate axis sketch supporting surface 6, a toe plate axis control point elevation surface 7, a toe plate axis control point dam transverse reference surface 8, toe plate section change control points 9, 10-toe plate trend control points 10 and toe plate axes 11 as shown in figure 1. The specific establishing method is that under a part coordinate system 1 of CATIA three-dimensional software, a dam axis 2 and a downstream axis 3 of the dam are established by taking a dam crest elevation surface 4 as a sketch supporting surface, and a panel sketch 5 is established by taking a dam cross section as the sketch supporting surface; creating a toe plate control point elevation plane 7 and a toe plate axis control point dam transverse reference plane 8 parallel to the dam transverse cross-section; a toe plate axis sketch support surface 6 is created from the previously created dam face sketch 5 and the dam axis 2.
Step two: parameters controlling the elevation of the toe plate axis control points, including toe plate profile change control points and toe plate strike control points, dam bar numbers and toe plate profile dimensions are created according to design requirements.
Step three: preliminarily drawing a toe board axis 11 on a toe board axis sketch supporting surface of the three-dimensional model skeleton of the panel dam. The toe board axis 11 sketch generally comprises a riverbed section, a left bank section and a right bank section, wherein the left bank section and the right bank section are terrain-adaptive, the toe board size change generally comprises 2-6 straight-line sections, and a certain angle is formed between every two straight-line sections; a certain point in the middle of each straight line section is used as a toe board trend control point 10; the common end point of two adjacent straight line segments is a toe board section control point 9.
Step four: each control point is constrained to "fit" with the toe plate control point elevation surface 7 previously created in the three-dimensional model skeleton of the face dam and the toe plate axis control point dam transverse reference surface 8 parallel to the dam transverse cross-section. Associating control surfaces (elevation surface 7 and dam transverse reference surface 8) of the toe board axis control points with elevation and dam transverse pile number parameters of the created control points; the purpose of adjusting the axial line arrangement of the toe boards is achieved by adjusting and controlling the trend of the toe boards, the embedding depth elevation and the dam transverse parameter according to weathered surfaces of all stratums in the geological three-dimensional model, so that the trend or the embedding depth of the axial lines of the toe boards reaches the design requirement.
Step five: creating a representative profile sketch support surface 12 of the toe board according to the type of the toe board; the flat toe board is a normal plane which is respectively taken as the axis of two adjacent sections of toe boards at the control point of the axis of the toe board; for the oblique toe plate, a plane is made parallel to the dam cross section and passing through the control point of the toe plate axis; aiming at the flat toe plates, the created normal plane 13 is required to be respectively deviated to the axial direction of the left toe plate and the right toe plate of the control point by a certain distance, the distance is determined according to the trend of the actual toe plates, and the toe plates at two adjacent ends can be smoothly transited, generally 0-5 m; a representative cross-sectional sketch support surface 12 of the toe board is obtained.
Step six: drawing a sketch of each section of the toe board on the previously created typical section sketch support surface 12 of the toe board; the typical section sketch of the toe board can be manufactured into a template in advance for calling, and can also be directly drawn on the typical section sketch supporting surface 12 of the toe board; after the representative section sketch of the toe board is drawn, the dimension parameters of the section sketch of the toe board are related to the corresponding dimension of the section sketch of the toe board.
Step seven: the regular toe plate entities 14 are generated from the typical profile sketch of the toe plate at both ends of each section of the toe plate using the "multi-section entity" function in the software.
Step eight: creating transitional profiled toe plate entities 15 between adjacent two end regular toe plate entities. The specific implementation process comprises the following steps: the geometric sides corresponding to the sections of the two adjacent sections of regular toe board entities are bridged to generate the surfaces of the transitional abnormal toe board entities, and the surfaces of the transitional abnormal toe board entities are combined into a curved surface by utilizing the curved surface sewing function in the 'creation type appearance design' module; the curved surface generated by the previous combination utilizes the function of a closed curved surface generating entity in a 'part design' module to generate the transitional special-shaped toe board entity.
Step nine: and establishing a project quantity parameter, and associating the created project quantity parameter with a measurement function, wherein the display value of the project quantity parameter is the project quantity of the current toe board.
Step ten: the toe plate floor plan and the typical section are generated by an engineering drawing module.
When the subsequent toe board layout or toe board section size is modified, the toe board three-dimensional model, toe board engineering quantity and toe board structure diagram can be updated accordingly only by adjusting the corresponding parameter values created in step 2, and thus, a large amount of time is avoided being wasted by re-modeling.
