Embodiment Construction

[0020] The present invention is based on the 3DEXPERIENCE Platform's BIM rapid modeling method for arch dam hubs, as shown in the attached figure 1 shown, including the following steps:

[0021] S01. Import the terrain elevation point data of the hub area into 3DEXPERIENCE Platform, generate the topographic PHM surface or triangular mesh surface of the hub area, and create a 3D engineering geological model of the hub area;

[0022] S02. Create upstream control points and downstream control points of the reference arch dam hub in the three-dimensional model;

[0023] Specifically, the coordinates of the upstream control point and the downstream control point are geodetic coordinates.

[0024] S03. Create UDF knowledge engineering templates for different structures of the arch dam hub, the input parameters of the UDF knowledge engineering templates are associated with the coordinates of the upstream control point and the downstream control point;

[0025] Specifically, the UDF...

Abstract

The invention discloses an arch dam hub BIM rapid modeling method based on 3DEXPERIENCE Platform, and relates to the field of water conservancy and hydropower construction engineering. UDF knowledge engineering templates of different structures of an arch dam hub are created based on coordinates of a upstream control point and a downstream control point, and preassembly is carried out to obtain a datum arch dam hub part template; the datum arch dam hub part template is utilized to change the coordinates of the upstream control point and the downstream control point; corresponding characteristic parameters of the datum arch dam hub part template are adjusted by combining the characteristic parameters of the needed arch dam hub, and a needed arch dam hub model is rapidly generated, so that the problem that rapid modeling, rapid display and rapid repairing and reusing cannot be achieved in the project proposal or planning early-stage scheme decision comparison and selection stage is solved; and the method is suitable for water conservancy and hydropower engineering construction.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower construction engineering, in particular to a BIM rapid modeling method for an arch dam hub based on 3DEXPERIENCE Platform. Background technique [0002] 3DEXPERIENCE Platform is a collaborative environment platform that can provide software solutions for various fields; it can meet the collaboration among engineers with different roles and solve industry problems and challenges. [0003] An arch dam refers to a retaining dam that bends upstream on a plane, is curved, and can transmit part of the horizontal load to both banks. It is a space shell structure. Usually, the arch dam hub includes barrage body, flood discharge structure of dam body, energy dissipation structure and power generation structure behind the dam. [0004] BIM is the abbreviation of Building Information Modeling (Building Information Modeling), which refers to the digital expression of physical and functional ch...
