N-dimensional feature modeling method for concrete dam construction system

Abstract

The invention provides an N-dimensional feature modeling method for a concrete dam construction system. The N-dimensional feature modeling method comprises the steps of N-dimensional information classification, feature information organization and coding, information storage and management and N-dimensional feature model construction. The method specially includes: taking a pouring bin as a basicunit, and dividing dam body information features into geometrical features, identity features, material features, accessory features, construction features and the like; on the basis of feature information classification, dividing construction objects in a concrete dam construction system into four types of construction resources, construction processes, construction results and attributes, subdividing each type of feature information of each type of construction objects, and carrying out layer-by-layer coding according to detailed information levels; designing a data table in combination withthe close relation between the feature information, and establishing a database to store information data; abstracting a dam body construction process into a simple process model from construction resource input to the construction process, and finally producing a construction result. The construction of the N-dimensional feature model of the concrete dam construction system is realized.

Description

technical field [0001] The invention belongs to the field of hydropower engineering construction and simulation, and in particular relates to an N-dimensional feature modeling method for a concrete dam construction system. Background technique [0002] Concrete dam is the mainstream dam type in water conservancy construction nowadays, and it has many advantages. However, in the actual construction process, the construction period is long, there are many participating units, and the information dimensions are complex. How to effectively integrate multiple information is still less researched in the field of hydraulic engineering. [0003] At present, people add time information to the traditional 3D model to build a 4D model, and then add cost information to the 4D model to build a 5D model, continuously add information to the model, and finally form an N-dimensional information model. N-dimensional information modeling focuses on the transformation of information in the who...

Problems solved by technology

N-dimensional information modeling focuses on the transformation of information in the whole process of engineering, and needs to consider the overall information organization and management. In the process of building an N-dimensional model, the biggest difficulty is that the information in the model is constantly changing with the passage of time. Difficult to maintain and update information
