BIM-based gravity dam intelligent design method

Abstract

The invention discloses a BIM-based gravity dam intelligent design method. The method comprises the following steps of determining a site selection area of a gravity dam; establishing a GIS system inthe site selection area, wherein the GIS system comprises terrain, geology and water system information of the gravity dam; associating the GIS system with the BIM; inputting related information intothe BIM to obtain recommended dam crest elevation, surface hole opening size and length information of the energy dissipation building; building a relationship among a water system, a terrain, the orifice size of a surface hole and the length of an energy dissipation building in the BIM, and screening out a river reach meeting the drainage length; building built-in relationships between foundationsurfaces and terrains and geology in the BIM, and screening out river reaches meeting terrain and geology conditions; and building a relationship between the model and a foundation surface, dam crestelevation, orifice size and an energy dissipation building in the BIM, and automatically generating a model based on the river reach obtained in the previous step. According to the invention, the design of the gravity dam is intelligentized, the rapid establishment and updating of the model are realized, the modification is convenient, the project planning period is greatly shortened, and the design efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy and hydropower engineering, in particular to a BIM-based intelligent design method for a gravity dam. Background technique [0002] Gravity dam is a traditional type of dam. The dam generally uses concrete or masonry as the dam body material. It has a simple structure and is convenient for construction. It is a rigid dam with good integrity. This type of dam is commonly used for medium and high dams. At present, the highest gravity dam has reached 285m. This type of dam is used in domestic large-scale hydropower projects such as Huangdeng Hydropower Station, Longtan Hydropower Station, and Three Gorges Hydropower Station. [0003] Gravity dams are divided according to their functions, and their structures include non-overflow structures, surface-hole structures, and energy-dissipating structures. For commonly used hydropower buildings, surface holes are usually a very important contro...

Problems solved by technology

[0007] It can be seen from the above methods that the design method of gravity dams has begun to carry out three-dimensional design, but it has the following shortcomings and limitations: 1) Modeling and model modification are difficult and inefficient

2) The existing models are mainly used for 3D drawing and effect display. In the actual engineering design process, there are still great deficiencies in engineering quantity statistics, structural calculation and reinforcement; 3) It still requires a lot of human resources to participate 4) Did not make full use of GIS for intelligent design
